Mufflex Group Purchase
Saw where www.fasttoys.net is having a group purchase on Mufflex products. If you are interested and want to save some money give them a call at 204-955-4896. I will be getting the Mufflex 3.5 inch exhaust system for my Trans Am. Going for 400HP. Hehehe. Allen

Do you have a direct link to the 3.5" exhaust system? All I see is the 4" mufflex.

3.5" systems
As mentioned, just get the part # from the Mufflex web site and email us for a quote. Mufflex has 8 pages of products for the Fbodies and we do not have them all in our online catalog but everything is included in the GP 
Thanks!

Thanks!

My 3.5 inch Mufflex exhaust system showed up today. Fasttoys is a good company to deal with. Good communications all the way through and the product was delivered as advertised.

Is it just for 3.5's or 4' units as well? I see no reason not to get with a 4 incher right out of the box.

It was for any Mufflex system 3.5" or 4.0". The reason I went with the 3.50" is because of the size charts versus horsepower/cubic inch put out by Walker and Magnaflow. Their charts showed a 3.50" system would work best for me. Allen

I know this thread is a little dated but Fast_Toys, can you get a 4" single inlet, 4" single outlet Spintech Muffler? If you want I will email you as well. Thanks for your time-Bryan
