I'm gonna be installing a catback system on my car soon and a header but with the stock downpipe, will this hurt my performance?

 

our stock dps are very restrictive however this will be a good performance increase over stock. if you dont have much money i would suggest an lsj downpipe, its slightly bigger and you can find them cheap used.

 

Moneys not an issue, just looking for something with a nice sound and not to loud or raspy, I have the megan exhaust ordered and from the clips online it doesn't sound to bad, the header is a cheap ebay job but I was thinking about getting a different one with a downpipe, what would u suggest?

 

Yes, stock LSJ downpipe is best bang for the buck, especially if you own an 08 with two cats.

I'm running GMPP honed mani with LSJ downpipe and stock catback. Most replace the catback first for the "sound" but if you really want performance, upgrade the manifold and downpipe first. The stock catback really isn't that restrictive.

 

and zzp header and dp????? well dp is almost the same as the lsj i think.

zzp header dp combo

i have a stock lsj downpipe if you want it

 

I would definately upgrade your downpipe at the same time as the header. Also be prepared combined with the megan exhaust your car is gunna be really loud.

 

how much u want for it? and is the lsj downpipe much different that then one on my 2.4?

 

I got a lsj downpipe today, gonna put it all on the car when i get home in a couple weeks
