Would true dual 2.25" flow enough to handle 325-350RWHP? Or will I need to go with 2.5"? I want to do my exhaust once. The plan is high flow cats, Magnaflow midmount and no mufflers in the rear.

Thanks

I scored a deal I couldn't pass up :D

And hey - what are you doing in 2 weeks - there's some of us getting together in Minneapolis area for CarCraft Nationals and a BBQ on Saturday. Check out www.midwestthundercats.com for details.

2.5 would be my bet why do the exhaust twice? 2.25 is plenty enough to flow a stock motor with some bolt ons but if you going with forced induction I'd be going with 2.5

Which is why I asked - I haven't done exhaust yet and only want to make 1 trip to the exhaust. This way I can do it right the first time :D

try to get a mandrel bent system if going 2.5... then you'll be fine

if you aren't hackin the cats, look into some magnaflow/carsound high flows to keep it legal and not pollute anymore than we have to. JL posted some really small packaged ones he found for a decent price a while ago

What about running like a big single exhaust since your going blower. Maybe a single 3.5 or 4?

If you look at the original post date, it's for my 96 :p The white car has 2.25" true dual so I'm hoping I can get away with it if I do get a Vortech.
