I am thinking of ditching my dc sports header and greddy catback. I am thinking of getting 2.5 kteller piping a jdm itr header and a es tuning oval.
My question
1. Has anyone tried this setup
2. Will this be way too loud
3. Should i go with a hi flo cat or a test pipe.
Thanks.

 

3. depends, do you want it to stay street legal? do you have to pass any sort of inspections? if the answer is "yes" to either of these, go with the high flow cat. also, if youre concerned about noise, a cat would probably be a bit quieter also.

 

add a resonator if your set up is too loud.

 

2.5in straight pipe FTW

 

whats a good resonator.

 

magnaflow makes some nice res.

 

Very good choice, you will see a # difference if tuned...I say you add a Hi flow cat, because you are in cali, and we all know how that is...also try it out without RES first, then if its to much for you add the RES....I don't think it's that loud...but that just me...I am running a Profab 4-1 header 2.5"to a 2.5" high flow cat and a custom 2.5" pipe on a 2.5" es oval. And I made good numbers tuned at do it dyno!

 

1. Probably
2. Everyones opinions on how an exhaust sounds or if it's loud is different. You'll have to goto a meet and check different exhausts out and have the owner rev it for you to form your own opinion.
3. If you really want the extra .25 whp and a chance of an expensive ticket

 

hey jdm bones how does your exhaust sound.
