exhaust size ?

Ditto on the 3" and mandrel pipe. A strong 468 can even use 3.5" to the muffler and 3" tailpipes, but either way 2.5" is completely inadequate. I myself cant stand Flows, but thats a personal preference. Go with what pleases your ear.

I don't mind 3" pipe. I was looking for something that fits well under the car. I don't like mufflers that hang down that's why I was looking at flowmaster that tucks well under the car. I'm openminded. This is a street car what fits the best. I've lowered the car about 2.5" and leveled the back to match front. Were can I find mandrel bent 3" pipes. Thanks for the help I'm going with the 3" pipe now.

One possibility for 3" mandrel bent for a 71 BB Camaro. Ive used stuff from these guys and had no problems. Several muffler options as well.

If you have ground clearance issues, you can check out spin tech. They have oval pipe for added clearance. They also sell mufflers, bends, transitions and made to order custom pieces.

Or you can go it same way that I did: I fab an 4" exhaust on 2 gen camaro with 2 set of mufflers. A pair of bullet race mufflers and big (cant remember Fm model) mufflers that go's in trans tunnel next to driveshaft, mufflers are it they own place under back seat and tails are coming under rearaxle with a little twist and coming out rear around original fuel tank. Owner later wanted tails to be 4.5" stainless.

Pictures: in here

There is no pic of those ss tails, for curves I used Patriot exhaust 4" madrel bend U-s, used 3 of those.

At first time I did an 3" straight pipe, no curves and round mufflers at the back, now with this new we have more clearance. This is a street car, had no problems with exhaust at all. Tune is strong but nice.

We have bigger and more powerful engine so 3" was too small, pipes where all to way colored blue and where boiling hot even at the far end after little "driving" but its just right for you.

----------------------------------
Thats exactly what I did. 4" oval pipe headers to mufflers, 3.5" tailpipes. Several custom pieces made by Spintech. One was a pair of 4" round to 4" oval transition bends. And the angle of the bend was specific to my setup. Thats how we got oval collectors on my custom headers. Spintech was great to deal with. Stuff got made right the first time and turnaround was very fast. I never would have gotten the car as low as it is without the oval pipe.
