Exhaust size?? - Hyundai Performance Forums

dadaman · 11-22-2002, 01:41 PM

I'm thinking about a new exhaust and the size exhaust pipe I have stock I think is 2'' would it be okay if I went up to 2.50 or would that screw up back pressure? The canister i'm putting on has a 2.5 inlet so i kinda want to run 2.5 all the way from the cat. thanks:smoking:

I almost forgot my tib is 2001 and manual 2.0 4cyl:dead:

are you going forced induction anytime soon? if not then i'd go 2 1/4.

2.5" will be fine as long as you add a resonator (like the Dynomax bullet) between the cat and muffler. If you're going to run no resonator then go with the 2.25". Personally, I think the 2.25" with no resonator is too high pitched and "zingy". I prefer the sound of the 2.5" with a resonator. The resonator will lower the pitch a little and add some backpressure to make up for the larger 2.5" pipe. Whatever you do, make sure someone welds up a system from mandrel bent sections rather than "crush" bending you a system. The resonator is available from Summit Racing for $31.95 (Part #WLK-24215).

your stock exhaust is 2.25" uhmm.... 2.5 will be fine.. im sticking with 2.25 tho... except my cat converter is a 2.5 hehe a lil better flo through there... i still need to get a catback though

No, stock is NOT 2.25"

uhmm well my 2.25" headers lined up perfectly with my stock cat converter..... so what is stock if its not 2.25"

The flanges lined up perfectly but the stock tiburon exhaust is not 2.25 last time I checked.

I would stick with 2.25" if you have no plans on forced induction but you will be fine with a 2.5" exhaust. If you don't add the resonator it will be pretty loud. What type of sound are you looking to achieve? Also what mods do you plan on adding?

I'm getting a cold air intake and just the exhaust for now. I want a deep sound but as much performance increase. I'm more after the performance side rather than looks and sound. so any tips are awsome thanks! oh and what other mods can i do to increase perfrmance that are not to bad on the wallet??? thankx:evil:
