spin tech any good?

 

I've got a 4" Spintech muffler behind a 4" single exhaust on my 83 TA. Sounds pretty wicked.

Seems to flow good also. Running high 11's through full exhaust.

 

Do you have the oval pipes?

I was thinking about going with dual 2 1/2in with 2 mufflers under my 84camaro.
Ground clearance problems with round dual pipes.

 

I have long tube headers and a Mufflex exhaust. 3" Y to 4" single exhaust. No CAT. Clearance is good. No lower than the header collectors.

The system is easy to install. However, aftermarket torque arm clearance may be a problem.

right now i have headman shorty header with collectors welded to 2 1/2in pipes to about the center of the car with 2 pro flo mufflers. i have about 7-8in of clearance on the passanger side and about 5 in on drivers side, i though i wouldent beable to get the oil filter off if i put the pipe too close to it. i plan on moving it up soon though and alittle to the side.
