ok i guess they stopped making the nismo exhaust. an i got an offer i couldn't refuse for it. so now i have some money to invest in my new setup i have a gtm stage 2 twin turbo kit with 3 in down pipes an i track the care so weight is a big thing to me. so was thinking of running a Tomei Expreme Titanium Exhaust. but not sure if their will be enough flow also what y pipe has a 3in starting point.

 

just have an exhaust shop build you an aluminum exhaust. past the downpipes, the temps are low enough for aluminum and it will be the lightest route.

Lot of companies make aluminum mufflers/ resonantors.

 

nice i like this idea thats why i asked more heads are better. but what size duel or single tip?

 

dam no more input come on guys

 

That's purely preference , to me a single flows better with FI. Get your self an exhaust muffler which ever you like (hks, greddy ect) and have a shop weld your piping .
