Hey guys, my engine build is finally done and I need some advice for exhaust. Right now I have just a straight piped 2" exhaust with no resonator. I know I need to go a little bigger, but how big? Also obviously this exhaust setup is NOT mandrel bent. Should I upgrade and spend the extra 300 bucks or more to get a nice name brand mandrel bent system? And how big should I go. 2.5" or 3"?

To help with your suggestions this is my setup.

Fully built d16 Vtec top to bottom. T3/T4 turbo .63 trim. Greddy fuel management bla bla bla. Basically I have everything you can buy besides an LSD tranny and a throttle body. I'm going to push up to or around 12-18 psi, (12-15 dd setup) depending on situations, maybe even low 20's once its dyno tuned. let me know what you guys think about exhaust choices. Thanks!!!

 

on that much boost, i would go for a 3", and DEFINATELY go mandrel bent.

 

come on Sac, my wallet just made a face at me! lol I knew down deep it would be that way tho [:'(] I guess next question is, where to get a 3" exhaust system that is gonna sound hella deep.

 

Check out Thermal R+D

 

Wow just got off the phone and the Thermal is 615 bucks [:@]

 

i would do custom or maybe Greddy Evo TT. (Turbo Tuned) but its not available for your app yet. no word on when, but if its out before you buy, ill give you the heads up.

 

i would go with 2.5 inch mandral bend, i mean this is a 1.6l sohc not a 2.2l dohc

but i could be wrong, i think that 2.5 would hold you up pretty nicely

 

2.5 would be fine, but at 18psi, it will start becoming a pretty big restriction.

 

Look around for a Tanabe system. You won't regret it.

 

I checked out tanabe, they don't come in anything bigger than like 2.2"
