Tech Spin Mufflers

BGTV8 · 12-01-2014, 03:42 PM

Has anyone used these mufflers .... I was warned at my last race meeting that the noise meter had logged me at 94.7Dba and our "put your car on the trailer and go home limit" is 95Dba, so I have been researching more efficient mufflers and found these.

Does anyone have experience of a road or dedicated race/track car ??

Hmm, i've never heard of these. What system are you running right now?

It is a full-race system with 1.75" primaries, 4-into1 collector with 3" outlet, then into a Magnaflow 3" in/out and 14" oval body on each side.

I could go to an 18" long Maganflow oval-body but there is a chassis member in the way and I don;t want to cut/shut it to fit the muffler in, so started looking at alternatives and found these.
