SLP Powerflos hit subframes
LM1s getting too loud cruising w/4.10s. Tried center inlet/outlet Super 44s, they were too wide and hit subframes. Now spent $ on Powerflos only to find they hit the subframe as well so are rotated a bit causing them to occassionally scrape. No mention of this in any ads for the product. Any suggestions. Thx.

Try an off set flowmaster. Mine were straight thru mufflers just like yours, but the muffler shop was able to fit them with about 1 inch of space between the driveshaft and the mufflers, with room away from the subframe. There's room right in front of the rear axle, but you more or less have to rearrange the pipes so the mufflers can stay right there in square void right in front of the axle. They'll fit, but a shop is probably going to have to fix it up for you with a little cutting and bending.
Did you already weld them in, or are they just bolted in place of the SLPs?

I know. It just parsses me off that they say it will work with 99-04 stangs and they don't. They atleast should put a notation in the ads about them not fitting.

Rebel, you butthole! I agree, but the Powerflo muffs cost less than a Adrenaline catback and I wasn't expecting them to rub. Prolly coulda used Adrenaline muffs w/ some fabbing but already cut the pips some trying to make the flows work and didn't want to cut more. I'll see if I can whoop up some pics.

I had Powerflo's on mine for a bit and was disappointed with the fit. They would fit just fine if the pipe passing through were parallel to the outer body (as on the LM mufflers). Due to their weird fit, I think they took away about an inch of clearance compared to LM1 or 2.
