So i decided that me and a friend will be doing my exhaust on my sol. I'll be getting 2.5in piping from SummitRacing (its 10 min from my house). the local muffler shops are asking for ~$400 for the full exhaust. And i can get 4 feet of 2.5inch tubing for 13 bucks.(http://www.summitracing.com/parts/SUM-640025/) So I believe its worth a shot.


The questions are:
1. I have a turbo downpipe that is 2.25inches. would it be a good idea to go 2.5inches after the downpipe? or make a bigger downpipe? will it really even matter?
2. Does the size of the cat matter? when it comes time to getting smogged i want to be able to pass..there is some that are shorter than others. will any do?
3. I'll be installing a resonator to keep it as quiet as possible, should i instal one long one, or 2 short ones? I've read that different sizes change the tone at different RPMS..

I want this to be as quiet as possible. I wish i could leave it stock
Havent made up my mind about the muffler yet. still looking for a reasonable priced, and quiet exhaust.
I like my stock sounding exhaust. I like being able to talk to someone while on the freeway...lol


THANKS!

 

Thanks for the advice guys!
lol

 

HAHAHA so funny man love the sarcasm, sorry wish I could help if I knew **** about turbo exhaust set ups.

 

lol

Well i think i got it figured out now. I'll be going with a 2.5in cat, resonator somewhere after cat, and a vibrant stealth power muffler. I Like how quiet it sounds.
