Restrictive Mufflers

Interesting Ive got a tti sys in my 68 Barracuda with the turbos but there to loud for me. Its funny I was going to run a new set of ultra flows for the track but not now.

Grab a pair of cheap glass-packs and put them right at the end of the tailpipes as resonators. The difference will amaze you!
