Turbo 383 in a A-body Barracuda

The reason guys reduce the exhaust down is to get the exhaust to the bottom of the car. A bodies don't have a bunch of room to sneak the exhaust out by the firewall & bellhousing area. There will probably only be 3 Feet of reduced exhaust at the most. Once the exhaust is at the bottom of the car at 4" he can SPLIT the exhaust into a DUAL 3 or 4" which should work just fine.

This is one of the reasons guys use Twin Turbo's instead of 1 bigger single................Most of the time it is easier to sneak a 3 or 3.5" Down pipe by the firewall...............

I went with Twins for this reason. I couldn't figure out how to get the exhaust out of the engine compartment without chopping the car up alot! I am using 3.5" Down pipes stepped up to 5" Home made Oval exhaust tips.

I think I can get the 5" down under the front of the engine and split it to 2.5-3 down the passenger side of the engine without to much problems. Cuda has 2.5 right now out the back thru series 40 flowmasters and original square tips. I do however have a 3.5" setup with Race Bullet mufflers too. I may need to cut the passenger side inner fender and run it out there and over the front tire. Then I could route it back thru the inner fender where you would cut for a fenderwell header setup and drop it right beside the engine/bellhousing. I will have to wait for the 400 and get it in the engine bay to determine how this will be done.
