View Full Version : Flowmaster Super 40 on 350 tbi

I'm thinking about running a single 3" pipe to a flowmaster super 40 series with a dual 2.5" pipe coming out the back. I am wondering if this is a good setup on my TBI 350 Suburban. I will be removing the cat at the same time because i live in Florida.

I don't see why it won't work for you I bet it will sound great also

I have that muffler on my 95 Silverado 350. I have custom stainless pipes from the muffler out the back at 45 degrees at each bed corner. It sounds awesome the stainless gives it a totally different sound.

Decided to keep the Cat and im getting 2 22" magnaflow tips cut 45 degrees to run coming out the back. Me and my friends mess around alot offroad so im goin straight out the back to keep it cleaner. Also DirtyBlackZ71 I like your clear corners i might have to get some. They look really good on your black truck.

if you get them straight out the back you might crush them unless everything around you is dead flat, no ditches or anything. i've almost ripped my 45*s behind the tires off.

All we have here for offroading is mud and more mud and usually never go at any steep angles.
