I have a 05 LS Sedan and I just recently installed a K and N Intake. Im wondering what I should look into next for perfomance mods. Im new to the seen of performance mods so any help apprieciated. From searching I would guess a new exhaust would be the next best bet? thx in advanced.

 

what are you trying to achieve?

 

Yes, A cat back exhaust should be your next performance mod, and if you want you can do a header/downpipe combo

 

A new cat back would be high on the list I think. Catback on a stock 2.2 is only about 1.75". Whenever I get over bout 3 grand all I can hear is the hissing coming from the tailpipe.

 

go to this site and drool a little:

Im mostly looking to gain some more HP. But like I said im new to modding cars, so I dont know all of whats what. But for now im going to look into a new exhaust. This exhaust would work on my car correct? http://www.crateenginedepot.com/stor...P1379C146.aspx

 

Don't neglect handling mods as well. Get yourself some lowering springs and/or a rear sway bar, and you will be shocked at the difference.

As for exhausts, go with something thats 2.25". Any bigger and you will really lose low end torque.
