im new to this website and recently bought a 99 3.0 cl 4 months ago and did some some mods. i have a v2 intake and megan headers,(in that order) noticed alot in the intake but didnt notice that much on the headers.
thinking that the headers need the full flow im thinking i need a catback exhaust? but they dont have a catback exhaust for the 3.0 so i was wondering will any other catback application fit on my car
help??need some info

the reason i said that the headers didnt do much is because my best freind has a 98 accord sedan 3.0 and we race all the time. when i first bought the car he had a short ram and i had stock and he edged me at the end @ about 85mph, then when i got my v2 he got an axle back exhaust and i killed off the start and had him by a car @ 85mph, so thats when i knew the v2 did something. then i bought megan headers on ebay for $200 and we raced again and beat by pretty much the same amount maybe a little more.
so i was wondering will the catback exhaust help and if so what will fit?

 

it will help a little and if you want to go with a name brand cat-back system you will have to modify it to fit your car. No exhaust sytem will fit you car perfectly and noone makes one for our car. So buy a good muffler and get custom mandrel bent piping. shouldnt be more than $300 total.

 

get a high flow cat, and some custom bent piping for a custom catback. That's what I'm saving up for

I have a custom cat-back exhaust and a universal carbon fiber muffler.
I love it.

My suggestion would be to go with a custom cat-back and a Greddy muffler
(EVO2).

 

By the way, what color is your CL?

 

I think im pretty much doing the same thing I gotta replace an O2 sensor, then while im at it might as well get a high flow cat, bosal headers (only reputable company I can find for good headers for the 2.3) then custom make it from the cat all the way out. Anyone have any luck finding good cat's, test pipe, etc.. I need the single o2 knockout but cant dont wanna take a chance buying garbage, or something that will trip a MIL.

Get the muffer of your choice. Then go to a muffler shop and have custom piping put on your car. The install and piping should not add up to more more than $100 unless it's mandrel bent piping.

 

I am definitely in the club that getting the full flow (intake/headers/exhaust) is much more effective than each of the parts. I first installed an intake and then an exhaust. I noticed small improvements after each. But then I put on headers and I noticed a big improvement--it all just seemed to come together.

 

do NOT put a custom exhaust on your car, UNLESS it's mandrel bent, because you'll loose airflow.

 

I know, but oh wells, it's just for now. My car is straight piped, so a lil back pressure wouldn't hurt from the crappy piping, if I get any what so ever.

 

my car is black DivineCL with dark grey interior, i have 18's, custom grill, clear corners, not lowered yet, and thinking about bigger rims.

What do you guys mean mandrel bend custom exhaust? will the exhaust shop do that for me?

now if i do buy a universal muffler what brand should i go with?

for the high flow cat is there a certain specs i need to get. i havent got a chance to look down below to see if theres an 02 sensor or anything else coming out of the cat, what do i need to look for? and will the high flow cat pass inspection, i live in ny and they just passed a law this past january, for stricter emissions

What 'Mandrel Bent' Means


Have you ever wondered what companies mean when they say their exhaust systems are "mandrel bent"? For that matter, what does it mean when an exhaust system is made using a "CNC" machine?

"Most factory exhaust systems built through the '70s were pressure bent," says Stainless Works (Dept. ETD, 9899 E. Washington St., Chagrin Falls, OH 44023, 800-878-3635, www.stainlessworks.net). "Pressure bending is when a tube is placed into a die and a hydraulic ram, which has the other half of the die--or the shoe--is then pressed together to push the tube around the radius. Nothing is inside the tube to prevent the tube from collapsing or buckling, and the machine is completely manual--the operator indexes the pipe by hand according to an angle gauge in the end of the pipe. Not a very precise method of bending, but quick and inexpensive.

"Mandrel bending is when a set of balls, called a mandrel, is inserted into the pipe during bending. These balls are positioned and pulled through the pipe so that the bends are not deformed and maintain a close-to-perfect shape throughout the length of the bend. The pros are that the tube can be bent on a much tighter radius and still flow well due to the pipe being round and not collapsed. The [cons are that] machinery is expensive for a good-quality CNC mandrel bender with the appropriate tooling.

"CNC bending is when a computer-controlled set of motors indexes the head of the machine and controls the position of the tube and the rotation of one bend in relation to another. Essentially, the machine does all the work. The tube is cut to the appropriate length, inserted in the collet and the button is pressed to start the cycle. The operator does not touch the part until all the bends are complete.

"CNC mandrel bending is the best method for producing exhaust systems that flow and fit well. With a CNC mandrel bender, you can also bend thin-wall tubing so that [the exhaust system] weighs less. Being stainless, it will not corrode, so thin-wall tubing is not a concern for durability."

Stainless Works manufactures restoration and performance exhaust products, including complete exhaust systems, headers, tips, mufflers, clamps and flex joints, bends and tubing, header components and X and H crossover pipes.

 

You will find few exhaust shops that have the machinery for mandrel bent piping. I believe it's a really expensive machine that runs about $100,000 if I remember correctly. I think that's what the shop owner told me, I forget. But thats the price of a damn dyno!

 

Also, do you understand what mandrel bent means now? I could explain it in simple terms...

 

nope that pretty much says it all, thanks

 

Sounds like a sexy black CL. pics?
