3" Exhaust, cat-back. Prep for VQ35DE conversion

[HusseinHolland]

Put the resonator in today. Helped with the drone, but still need a quieter muffler. I have a new Solo Performance Stealth 25 from my X1/9 K24 build, so I'm going to swap that out next

[HusseinHolland]

Reworked the rear section to incorporate the Solo Perf. muffler. Dimensions are a little different - a little more rectangular in cross section than oval , so I had to cut & move the feed pipe and remove the stock exhaust hanger bracket to make it fit

Have to weld the rear hanger to the muffler outlet, then add a short section for the exhaust tip to clear the valance

Got the whole thing set closer to the rail, but with better clearance off the spare well

Left the innermost part of the bracket, so I have something to hang a support off of.

got it all tacked, now I have to weld it all & make a new hanger

I like how you have added that 4" extension that pushes the muffler up into the corner of the rear quarter and deck, it never looks good having the flat oval mufflers visible.  Pretty tight clearance, you might start smelling the melting undercoat.

Yeah, happier with the overall fit on this one. I was thinking about the upper clearance. With a hanger on the front of the muffler, the whole rear pipe/ muffler will get pushed very slightly outward & down a smidge. That will center the tailpipe a little better also. Still close though, so I may put some Volvo/FoMoCo heat shielding up above it.

Made a heat shield to go above & around the muffler, since it is now set so close to the frame/floor. Bolted in place where the original bumper shock shield was attached 

forward muffler hanger 

gaps/clearance off the subframe is still good

Just have to deal with the tailpipe now

Where did you source the heat shield material?

I was going to ask the same question.

All Volvos from 2000-on use it in the driveshaft tunnel & under the rear cargo/trunk floor above the rear muffler. I saved the sections from an 2004 S40T5 AWD when I stripped it for converting my C30T5 to AWD

Yeah, BMW uses sheets of that stuff and i squirrel away when I find it, just thought you might have found a source of virgin heat shield.
