Seems like a beefy part, but I dunno about those spinner thingies inside the muffler. Seems to me like they'd be even more restrictive than a regular "Flowmaster-esque" muffler. Hehehe, I made a word, cool.[img]/wwwthreads_images/icons/cool.gif[/img] Anyways, seems like it's high build quality, but I dunno about them. I'm still going with either another 40 series Flowmaster Delta Flow or a Magnaflow for my next muffler.[img]/wwwthreads_images/icons/smile.gif[/img]
How much do they want for one of these gizmos?
What did the SFA boys have to say about them?
285/75R16, 255/85R16, & 305/70R16 fit on a stock GM IFS fullsize 4x4 truck when on the stock 16x7 rims.
I havent checked out the sfa a forumn or clicked the link but Id bet your talking about the spintech mufflers, there big and bulky. think I read a article on them somewhere. guess Ill check out the link, yeah thats where I saw it i realy like that they said they turned out quite even through the went infront of the rear tire,
