I'd look into a turbo. You're going to be getting hot, if you aren't already. Then you'll be OK with bigger injectors too, later on.

Try a 4" exhaust and some injectors. Go with the DDP's. Maybe a stage 2?

dang! 25 hp gain is pretty nice! yea i have straight MBRP 4" right now. i plan on 6" flat tops later. injectors and intake? or what does everyone recommend. what about 330s? bad spray pattern? whats the best injector set for around $500?

i hit about 1000-1100 degrees max when boosting 30 psi. plate is going to a number 100.

I aleays thought that a 6" exhaust would make you lose power. But then again I guess if I had the mods dual k20s does I might need the 6". Hopefully one day I can get the old beast there!!:)

I was being sarcastic if you didn't notice.

The gain of 5" over 4" is neglegted with the stock turbo and its really small turbine wheel and exhaust outlet. 5" is 1.56 times the size of 4 and 6" is 1.44 times the size of 4". Above 500hp there might be a measurable gain going to 5" but it won't be noticable, and as a percentage it will be small. I wouldn't use 6" unless I had a turbo with a 6" outlet
