I am getting a universal Magnaflow high flow cat put in my car. I am goin to use the flanges off of the stock cat to weld onto the new cat...this way i dont have to ruin my headers and exhaust...exhaust shop is doing it for 150 installed

 

nice. what will the gains be with a high flow cat if u know? post pics when it's done!

 

it will give some gains in the higher rpms but i really want it for tone and loudness...plus the stock cat looks shitty!

 

Sounds cool...

 

... if they are legal in CA ???
Thanks,

 

yes they are 50 state legal...according to magnaflows website

 

i found the cat alone for $73 dollars on this site
http://www.performancepeddler.com/de...CT_ID=MAG53054
magnaflow lists this cat fitting our cars...i am buying this one and getting it custom put on using the flanges off the stock cat

 

any plans of before and after dyno? im interested if the gains are good

 

Nice, I was thinkin about doin this. Make some before and after exhaust videos!

 

this wouldnt happen to be a direct bolton would it? are u going to have weld it?

 

ordered from that site but i called and ordered it..dean the owner gave me the cat for $52.12 shipped...should be here friday or monday

 

getting installed 2morw

 

^ Sweet. Gonna be badass. It better make the exhaust sound more aggresive.

 

yeah UPS still hasnt delivered it yet..hopefully they will if not it will be installed 2morw

 

Update?

 

yeh i want an update too cuz im probably gonna do this mod...

tell us about performance but also about the sound please

 

x2

 

I installed a custom made test pipe yesterday, stainless steel with O2 bung(for check engine problem). Lost a lot in the low end, gain a lot in top end especially punch from 80-120. Rpm's climb up so much quicker, but again its a test pipe not a high flow catalytic converter, so with your setup you should feel less gains in top end, but still lose in low end.Also my tes pipe makes the car sound much louder, not ricey at all, just deeper, louder

 

I also want to know if there is any hp gains from this setup?

 

i will dyno afterwards...ups has still not delivered it...i think because the north was frozen all last week..when does low end even matter? When i get out of the hole it takes 5 feet to get above 4 grand...all i need is top end power..

 

low-end DOES matter... unless you neutral drop from 4k rpm, then you get tons of wheel spin and damage the tranny!

the TL is so slow out of the hole it's not even funny..

my exhaust didnt help low-end power and the high flow cat probably wont do any good... but oh well.. i can always catch up with those lil civics over 30mph

 

my car stalls at about 3k rpm...it spins in first gear so it goes right to vtec...i just feather it out...tell me why low end matters on my car

 

if it spins that much you might want to look into better tires....

i find low-end important when passing or something like that... when launching with sticky tires torque at low rpm is important also... we all know the TL is weak under 4k rpm

 

well i have toyo t1-Rs so i cant get much better...i also spin with drag radials on too...240 whp on a heavy fwd usually will spin a lot...

 

240whp... my bad

didnt know u add a whole lotta things done!

but i still say low-end is important (when passing, etc)

 

do you mean your car idles at 3k rpm? how did you manage that??

 

no he probably has an aftermarket torque converter that makes his car launch at 3k rpm instead of much sooner with the OEM unit... (my guess)


btw this afternoon i ordered a magnaflow 2.25" high-flow cat for my car... i cant wait to put it on!

 

hell yeah..where did you order it from? btw i have a stock torque converter...it stalls anywhere between 2750-3000...probably not right but thats what it does haha...

 

cant wait to hear how the Magnaflow cat turns out. keep me updated guyz

 

yeah im still waiting on it to come in..the day it comes in i am installing it...

 

wats the range of price on installation?

 

umm the guy thats doin the welding for me is charging $20...u just gotta know some people to get a good deal...

 

the cat is on backorder so i have no idea when it will be in

 

That's a pretty good deal where ure at. I charge my customer 130 installed with the High Flow Magna Flow with the o2 sensor bung hole.. MAGNA flow are probably the best Cat i've ever stock at my shop. IT helps alot. The great thing about it is that. Not only that the holocomb inside is thinner. you get more air flow and i pressure check it against the other brand its about 30 percent more flow and almost 50 percent against the oem. I highly recommend this cat..

 

I wonder if installing the aftermarket CAT and WS2 mufflers would improve the response and exhaust tone? I don't want it to be much louder just a deeper tone would be nice. Those G35's have a great sounding exhaust BTW!
