is there anyway u can make the stock exhaust louder?

 

replace stock cats with high flow cats or test pipes

 

will it change the sound of the stock exhaust tho?

 

stock with strup test pipes:

stock with FI high flow cats:

 

+1 Fast Intentions High Flow Cats... they will make the exhaust deeper and louder... test pipes rasp to much sounds nasty

 

I put some Fast Intentions High Flow Cats on a while back. It makes the exhaust a little louder and a little deeper. I also have a Z tube. You could throw headers on too if you would like.

 

yo did you get any check engine lights or anything weird at all? im thinking im going to go ahead and buy them after seeing the clip above

 

you should not throw any codes with high flow cats.

 

Some people have removed the resonater on their exhaust and welded in a solid piece of pipe in its place to make the car slightly louder with an otherwise stock exhaust.

Those who have done it seemed to have been happy with the results. Personally, I'll probably be going with a full cat-back system when spring rolls around.

 

replacing the resonator in the midpipe will cause rasp. i speak from experience.

hell, even people that have replaced it with a smaller resonator were not all happy. that caused rasp sometimes, too.

 

headers and high flow cats - similar stock note, hella lot louder.



oh yes, sounds good to remove the resonator!! (sic)

There is a sale on FI HFC's and cats in the vendor market place.

 

Yeah my cousin also had his resonator removed on his 06' g35c and it sounds horrible. Worst way to go.

 

I couldn't decide between Crawford or FI HFC's, but after hearing that video clip, I think I'm gonna go FI...

Thanks Patman!

 

Will I still pass smog check if I add Fast Intentions High Flow Cats? It is illegal? thanks.
