Default rwhp limit for 2.5" true duals

ive always heard around 450-500. ive seen cars make that with 2.5" duals. just wondering how far you can go before it really becomes a cork.

this is corvette related im trying to decide between the LG streets or a cheaper setup with 3"

keep in mind i will be running cutouts on my midpipe.

I would think 500-600 rwhp would be fine with 2.5s...depends more on the mufflers and the design of the exhaust system.

cool thats all the info i needed.

jay, i fabricate custom exhausts on the side lol. i am super duper familiar with welding aluminized pipe

if you do a search under my threads, i probably made one of the better true dual F-body setups i've seen on this site.

ive got access to a miller MIG that runs off 212 with gas, and i can lay a sweet continuous as long as my gaps arent too big, if the gaps are big, its tack/cool/tack/cool till the cows come home

again, thanks guys/gals? for the info
