So i will be dropping my 3 inch straight pipe with some magna flow mufflers and some magnaflow tips i have. the tips are a 2.25 like the stock piping on the tl i believe, will i be able to install these tips with my 3 inch straight pipe to my magnaflow mufflers? If so, is that the widepiping my shop keeps referring to? Another question is, what part number do you recommend? I'd like to see if buying the magnaflow mufflers on my own will save me more than spending 300 at the shop for them.
Why would you put tips that are 2.25 on your 3" exhaust? As for the mufflers, you can get them much cheaper online at places like Jegs. Get ones that have large enough in and out to match up with your piping you are using.

Problem with the tips is i bought them with 2.25 like an asshole. The shop where imma get my exhaust done said i wouldnt have a problem doing that so thats why i was trying to use the parts i already bought :/ In regards to the mufflers, im confused because when i go to actually look for them, they have the single to dual, single to single, and then their outlet and inlet s vary from center or one of the edges. so idk what is the difference and which i should go with for my car. I dont want to buy mufflers online and then be stuck with more parts that wont work for my setup.

Which should i get? or it doesnt mater? the shop is charging me 300 for both mufflers alone. I want to get the best deal i possibly can without sacrificing performance
would it affect my possible gains from going 3 inch on my straight pipes with smaller outlet on my tips??
UPDATE!
turns out my tips are 2.25 inlet and have a 3'' outlet, so if i stretch them (the tip inlets) i can basically make a straight 3'' from my straight pipes to my tip outlets?! if so, ive already ordered my magnaflow mufflers 3'' in and 3'' out so im set.
I highly doubt you will be able to stretch a 2.25 to 3" without tearing the metal. Just go buy tips that fit.
So are you running 3" to a Y then 3" to 2 mufflers? If you are that isnt needed. You could run 2.25 or 2.5 from the Y to mufflers. Muffler and tip choices will be cheaper and easier to find. As for which inlet/outlet to get, that all depends on who and how you mount them.

I was planning on running 3 inch straight pipe all the way through and hopefully manage to stretch the inlet of the exhaust tips that I have that are 2.25 stretch into 3 because the outlets are 3. I also bought Magnaflow mufflers 3 inlet and 3 outlet.

so you are running 3" to a Y, then 3" to each muffler? That is overkill.
And dont get your hopes up about stretching your tips. Best scenario is an exhaust shop cuts the tip just before it shrinks down to 2.25 and weld a chunk of 3" to it so you can use it.
3" isnt pointless when all the supporting mods are done. 3" to a Y then 3" to each muffler is pointless. Also, its easier finding 3" than 2.75 pipe (im running dual 2.25 which flows more than a single 3 and saw gains from it on my old 3.2)

Im gonna be running quad tips, down the line i plan on getting a CAI as well and possibly some headers. so i might as well do everything now and have a good foundation to my future mods. Thats my goal at least. And the can cut the tips!? thats fucking genius! i have nothing to worry about then. Its all just a matter of going to the shop on payday and doing the install! WOOOOT! im not buying an aftermarket resonator or cat though. would i need to or could those be stretched? or will they they just take everything off and literally run straight pipe from the cat back?
1. What is your current exhaust setup?
2. What part number mufflers do you already have?
You have a TL-P so I'd say unless you plan on nitrous or some major engine work, keep it to 2.5". Get headers, magnaflow cat, 2.5" exhaust with resonator and mufflers. Do it right and do it once.

My tl-p is stock exhaust. Reason im doing 3'' diameter piping is because ive read that on our cars we can go up to 3'' without losing horsepower or back pressure while also allowing our cars to breathe better. So i figured if i can allow my car to breathe better, and get some gains without damaging my back pressure ratios, i might as well go 3 inch. The mufflers i currently have are being shipped to my house as we speak. They are 3''in/out oval mufflers from magnaflow. As far as the magnaflow cat, is that really worth it?
You won't really be able to utilize the potential of the 3" especially since you are pretty much doing i/h/e. If you go above and beyond that, sure.
So youre saying that with i/h/e my 3'' setup is still pointless? it wont even make a good tone for noise?

Reason: i wrote the wrong thing due to me already knowing the definition of said acronym, just didnt notice
I see it pointless, unless you really want to squeeze out as much hp as you can. Tone wise, idk. I never heard the difference in piping size, only swapping out mufflers and what not
As fsttyms said, 3" piping is easier to find also.

alright, thanks for the input guys. as far as the cat and resonator, should i really consider buying aftermarket ones to go with my 3'' setup or can i use the stock ones? or is it just better to run straight pipe in its place as well?
If i were you i'd get some DC headers. Have the shop weld on a universal magnaflow cat, then weld on your mufflers. Leave the rest. You'll get good hp from the headers and cat, and some tone from the mufflers.
Also, you can't run 3" piping to your stock resonator. I think the TL-P exhaust is 2" only.
I just had my 3" exhaust done and for your setup of i/h/e on a TL-P, 3" is overkill IMO.
Ok. You need to start over with ALL your information. Is what is below correct?
1). You were/are planing on running STOCK CAT and RESONATOR with 3" pipe???
= Pointless You are wasting money on the exhaust work to keep those. Get a high flow cat and ditch the resonator, or at minimum get a resonator with the correct inlet and outlet as the pipe you are using.
2). You are running 3" pipe to a "Y" then 3" to each muffler which is 3" in and out?
= Pointless/overkill Overkill, get smaller pipe from the Y and smaller in and out mufflers. It will flow better being NA with your mods. Also to really take advantage of this exhaust you NEED to do other things like port and polish/gasket match intake and exhaust side of heads. Also redo your header to get rid of the tight U that the rear makes into the front pipe and have it come together in a smooth transition Y.
3). Then you have 2.25 inch tips what you want to run QUAD (read, 2 tips per side) on a bumper that has a SINGLE cutout on each side?

Why? it wont look right
if i need to get an aftermarket cat, then i guess i will. i was just asking questions. i got the money for the cat if i need it. how much do those usually cost? and no, my tips are 2.25 inlets and have an outlet of 3. and headers id need to get down the line.
In regards to the high flow cat, which one should i buy? im looking everywhere online and i cant seem to find one to match my 3'' specs. the mufflers are already mine since i special ordered them, the tips ive been having them. the shop told me they can do some custom widepipes to install. now, the cat, should i buy one that is the same spec or buy one with less specs and then make it so that it increases in diameter as it goes down the pipe? im rather confused now.
well, to chime in here on another option altogether, unless you absolutely need the look of having both tips on the rear of your vehicle, you might consider single 3" all the way back to one muffler (tips is a matter of your preference ... mine is just the piping after 1 muffler into where the tips would be under the bumper & the plain look doesn't bother me). saves you the price of buying 2 mufflers, 2 sets of tips, & the splitting of piping into 2 at the rear. I am running this single setup as are a few other members & i enjoy it, & compared to stock piping & mufflers after stock cat i gained 2.5 tenths in the 1/4th mile with new single 3" (still running stock cat ... dc headers up front on both setups). & on a side note, as for test pipe i have ran with a test pipe in place of the stock cat & noticed, or should i say gained, nothing on my 1/4th mile in near same weather conditions.

Thanks for the input. i just need someone to answer my high flow cat question though. i want gains, i want tone and i want sound. i dont want a ricey 4cyl tone, and i dont want a ricey "its over 9000" sound in volume either. I just want a good high flow cat that i can match up with my parts that i already own. (mufflers x2 tips x2)
Custom is a hit or miss. Will it rasp? chances are high. High flo cats are pretty expensive, straight piping it is fine and will make the car plenty louder of course. HP difference is minimal. All depends if you're fine with the carbon monoxide you'll be breathing at stops.
Just get a magnaflow universal cat. Again, if I were you I'd get DC headers, magnaflow cat, 2.5" piping, magnaflow resonator 18" or longer, and whatever mufflers you want.
You need to do this at the same time. Don't slap on big 3" piping after a tiny oem headers.
if i need to get an aftermarket cat, then i guess i will. i was just asking questions. i got the money for the cat if i need it. how much do those usually cost? and no, my tips are 2.25 inlets and have an outlet of 3. and headers id need to get down the line.
I understand your tips have an outlet of 3, but before that it is 2.25" which is a bottlekneck.
And all this is kinda pointless without headers. Especially with that size exhaust
The outlet size of your tips does not matter, it is the inlet that does.
Like others have mentioned it is pointless without headers, and aftermarket cat or no cat.
The shop is just telling you what you want to hear.
I dunno why you want to stretch things, just get the right size to begin with.
Like others have said get dc or ebay headers, magnaflow or XLR8 2.5" cat and 2.5" exhaust with 2.5" resonator. You can go single all the way back to 1 muffler or split from the 2.5" into two 2.25" then 2 mufflers.
3" will be louder(more obnoxious), weigh more, have less ground clearance, and cost more. 3" is worth it with Type S motor and full bolt-ons, otherwise get the other parts first.
I have pretty much full bolt-ons on a 3.2 with bored tb, ported IM, plenums, ported runners, etc. I went from a 2.36" to a 3" and only gained maybe 10 hp and tq or less throughout the entire rpm band and even less at peak 6-8. I even modded the headers/down pipe and added venturi effect to try and increase velocity.
I wonder if my ECU needed more time to relearn before going on the dyno. Also need to relocate my IAT sensor to the silicone coupler.

ill be getting headers soon. so would i be charged more if i install exhaust with the tips, mufflers and a cat and then do headers afterwards? if so, then ill just wait it out and do the install later on in january.
Thanks! will do then. So ill just post pone my exhaust install, untill i buy the headers and the cat and then im set to go! Nice clip btw ^ So in the mean time, ill focus on wraping my car and doing other cosmetic reviving
Mine is pretty loud. If I have female passengers they might need ear plugs hahahaha. You can really feel the exhaust in your ear drums. Feels like your ear will explode, I love it.

And bro, if i only knew what half of those things were and what they did, id feel like a boss. seems like u put in lots of work on the car.

I didn't know anything when I first joined the site. Learned a lot in the last 12 years. You will get there.
Exhaust isn't as complicated as it seems. You just can't let the terminology confuse you and think of it logically. An engine is a big air pump. The intake side draws the air in and the exhaust draws it out. You want to maximize both ends and flow equally in and out.
Another example is think of an exhaust as a straw you are blowing through and what creates most flow. You want to remove bottlenecks and restrictions. First restriction is header, then cat, then exhaust.

Gotcha! that helps a lot more in narrowing down my mods and what steps to take. Hopefully i manage to get my injen sri im hopefully buying from another member here, (if he finds it) then all id need on the list is my headers and high flow cat. then ill be able to run my 3'' exhaust like i want i suppose. Should i run high flow cat or a test pipe though? what are the differences in performance and/or sound if any?

2003 tl-p magnaflow spec opinion/help
if so, ive already ordered my magnaflow mufflers 3'' in and 3'' out so im set. 
(im running dual 2.25 which flows more than a single 3 and saw gains from it on my old 3.2)
and yea @HairyMonkey019, that sounded vicious
