SPPD

strait gm stage 1 my best time is in my signature. I have added the k&n intake and a custom exhaust, but my car broke at the track before I could run with them.

auto trans - gm upgrade only - 14.1 at 98 mph.

FWIW: I believe I would be much quicker if I had a little more track experience, and better tires. Nothing I would do would allow mw to get good traction. I was ripping the tires in 1st, and from 1st to second. The power is there, the experience and traction is not.

Alright cool, If i can confirm the catless DP from Dejon doesn't throw a code im going to mod the exhaust where it looks factory but will be 3" downpipe back and go through the stock muffler so it's a straight pipe but looks stock :)

No need to go through all that. The biggest "restriction" is 1) the stock DP and as a possible 2) the 2 1/2" piping size of the stock exhaust. If you want to keep the stock look then start with the DP. If you want more power then go w/ the 3" catback of your choice. BTW I've been to the dealer a few times for warranty work and regular service visits and they've never given me any warranty hassles, even w/ the obvious Hahn logo on the FMIC . Just get the GM upgrade done 1st to get the best bang for the (warrantied) buck.

idk about the gmpp tuning, but on a hp tuned car the catless 3"dp can add around 10whp up to 15 if tuned. the tuned cars when adding the catback aswell only gain a couple whp even tuned because our stock exhaust is actually pretty good and is straight through even the muffler. I would expect a high 13 to low 14 with the gmpp upgrade but there is no other gmpp stuff for the ss.

to add to jaxson and the other poster,there is gmpp's out the for the ss...for the lsj cobalt ss(supercharged) when it comes to intakes and such.
