yah im going to be getting a cat-back and high flow cat over the winter need help? which system makes the most power and also is not going to cost me major bling! currently i have 2 1/4 piping with a magnaflow muffler with a resignator instead of a cat! so by purchacing a cat-back should there be any gains? or is it all show?

ohh yah i have a 2000 ls

not like it matters but im getting a dc header tooo!have aem cai

 

Im also running a 4-1 dc header adn im running the apexi n1 exhaust with it on a stock cat and it runs pretty good and sounds nice as well. It will run ya about 500, but if ya want to go with a different company hks and greddy also make good exhausts that produce good power.

 

You won't see huge gains.

You basically have an "exhaust" right now.

It will just be a different exhaust.

For a LS with boltons, they are all pretty much the same, just get the one you like based on looks / sound.

 

I love my N1, oh and DC headers dont make much difference at all with LS headers, it would almost be pointless, u would get sum power but none of n e significance, just tryin to save u some money

 

don't know about no power cause i have an obx header , before it my best 1/4 time was 15.7125 and now its a 15.4 nothing was changed!!!!

 

I love my thermal R&D and have not considered anythign else since. i had two other mufflers before and they all made the car sound cheap

Thermal Das Good Ya

 

how much for that?
