just installed a c-a header, 3.0" catless downpipie and 2.5 pacesetter monze exhaust last night on my car. its loud, really loud, but raspy. I mean civic on steriods raspy, but fast. lol. any ideas on how to get rid of the rasp? I heard about using a resonator or should I just get a new muffler? thanks for the help.

really, you'll have to ditch the monza. i had it on my 2.2, and was raspy as all hell. but, what i did that helped big time was to put a resonator in since it doesn't have one. other than that, a different muffler. nothing else to do.

i had a 12" but i would even try to get a bigger one if you can. the 12" made it better, but still didn't sound good. catless dp is making it even worse. the pacesetter exhaust is a compromise. it's better quality than most people give it credit for, and sounds pretty good by itselft. but once you add other exhaust parts it really sounds like crap. but you can't expect it to do everything for half the price of most exhausts, and sometimes 1/3 the price.

on the 2.2, i just went with the cheapest parts out there, and in turn i had a car that sounded like crap. on the 2.0 i spent the extra money to get good stuff, and it's just so worth it. the car sounds great now. but that also cost a LOT more money too. but so worth it.

how much do they restrict flow?

it's hard to have it all bro. with your setup, you have 2 choices. free flowing, and sound like ass, or sound good but start adding restrictions. but if you get a performance hi-flow resonator it shouldn't really add much restriction at all.

you might put more money in making the thing sound good then just selling that catback and go n buy a corsa sport....sounds 1000X better

do you really think that would help? it the d.p. and header adding the rasp. will the corsa hide it?

yea, will make a huge difference bro. i had the cobalt addiction set up last time, and this time i have the zzp mid lenght and downpipe, and also a magnaflow cat. sounds SO much better this time around. i think it would be worth it to get a better exhaust.

i can get a resonator for under 50 bucks, and I weld so installing it is no issue, I will see waht it does, if it doesnt help I will get a new catback system

yep. after that i would try a better muffler.

well for 100 bucks to try to get it to sound better, then just jumping to a 700 dollar setup if okay in my books

A three inch catless dp?!

On a LE5?


For what reason are you revving to 9k?

:lol: Lose a 1/2 inch on that downpipe, put a resonator in, call it a night

Unless you are turbo you really don't need 3 inches of dp but hey each to its own...

Any 4-cyl w/o a cat is gonna be raspy. I have a CA header, XTC 2.5" de-cat downpipe and an ARK N2 cat-back, and its waaaay loud and deep, but it gets raspy as hell at higher rpms. But I actually like the rasp myself. Sounds aggressive IMO.

My question to you is though.....why did you get a header w/ a 2.25" collector, bolt that to a 3" downpipe, and finish it off w/ a 2.5" cat-back???

Haha what ^he said. A cat or huge resonator is a must in a 4 cylinder.

Yep. I have no cat, but the N2 features a nice resonator. Either way, my car is loud and obnoxious even at a stand still, lol. Owell, your only 21 once. I'll "refine" my car tastes when I'm older.
