get the LSJ catback. i have it and love it. gives a nice tone with a catless DP and lsj ex mani.

 

2.5" is good up to about 250 hp, so I would only assume 2.25 would be good for around 200, and I know no 2.2 is even close unless you're running a very large shot of nitrous. Any NA balt would do better with a 2.25.

 

i want the tsudo when i can afford it

 

Go to a good muffler shop and get a custom system compression bent up...it should be way cheaper unless the shop is a rip-off.

I just got 2.5" full exhaust, header dp is 2.5", got a 2.5" cat, 2.5" pipe (compression bent though so not true 2.5" at the bends), and 2.5" dynomax ultraflow ss straight through muffler.... I don't notice much low end loss at all, and mid to top end power gains, and I'm only pushing maby 160hp so far, but hopefully much more soon.
