Thinking about picking up some LT's and go true duals, just had a couple q's

-Should I run 2.5" duals or go for 3"? After I complete my build I'm only looking for about 500whp MAX. I understand the 3" will support more power but if I can run a 2.5" for less money,have better ground clearance, and without sacrificing any power why not? also on the true dual cars I've heard in person the 2.5" vs 3" with the same dynomax bullets on both, the 2.5" did sound cleaner and had a more liveable volume to it. so pretty much just wondering if anybody thinks I will hit some performance ceiling with a 2.5" true dual setup for my goals

-also does anyone have any sound clips or opinions on true dual setups on LT1s with anything but bullets? I understand bullets are cheap and have better clearance, but I'm looking for something different, whether it be one-chamber flows, 40 series, etc

I do not think ull hit a performance ceiling with duel 2.5.

 

are you running a cross-over pipe?

sounds good

 

Nope, straight pipe. I was going to run an X-pipe but ran out of funds, I may do that down the road.

 

To make 500rwHP through your A4 your going to have to be making ~600HP at the flywheel. That requires a large exhaust. Nitrous needs a "big" exhaust system. You're at the point where the dual 3.0" system may not be irrational.

 

While the 2.5 may be adaquate as I said, I also agree with injuneer mostly because I went with 3 inch due to nitrous also. All that extra exhaust has to go somewhere!

 

3 inch all day with N20.
