Who makes 3" exhaust for our cars?

Post by Hillbilly on Tue May 31, 2016 6:08 am

Torque tech has decided to go out of business right before I got my exhaust ordered. Who else makes 3" exhaust specifically for our cars?

Torque Tech does make some nice stuff.  Did your engine dyno over 650 hp to require a 3" exhaust.  Its a snug fit in any car and usually not worth the headache unless you need it for your hp range.  And not to mention the loss of some low end torque which is best for a street car.  2 1/2" up to 500hp. 3" over that is a good rule of thumb.

The current motor no, the 496 I am piecing together, yes. Like I said it looks like torque tech is going out of business and no longer has exhaust.

My camaro had 2.5 just to drive around on and lost 26 wheel hp. I went to 3.5 on drag week. That engine makes 1000 on the bottle. This chevelle engine should be low 600s with AFR 265 ovals and a hyd roller.

I installed 2.5" Magnaflow's for a 68-72 Chevelle and they fit great on my '77. Not sure if their 3" will work but going with 68-72 year could add another option to search for.
