Max muffler size in the sills?

[Sneaky Pete]

In another thread within the SRT section we are talking about how to quiet our Vipers down for use on tracks with stiff noise limits. I have some ideas (see the other thread), but I dont know what will fit w/o taking everything apart and measuring, which I'm sure some of you have already done...

Can anyone tell me what the max size would be for a muffler to fit inside the sills on a gen 2 with side exhaust? Looking for length and width. If I have to I can always use two separate units together to maximize the space available.

Its not a one-size fits all in there, the bulge towards the rear of the sill accommodates for a lager exhaust component than the flat front portion that houses the cat.

6" OD will fit behind the bulge in the sills,

4" OD will definitely fit in-place of the cats
I think 5" will fit but i havnt verified

Thanks Dom, that's the info I was looking for. As I suspected, it appears I'll probably have to use two mufflers on each side.

Looking forward to your side exhaust writeup!

That's exactly what I did. Used a bullet muffler in place of the cat running into the mopar/borla muffler and into an H-pipe right before another bullet muffler and finally out to the tips. I love the way the car sounds too....it's a straight through system with a nice DEEP rumble to it. When I get her fired up again I'll make a video.

I suggest buying an engineered system from Corsa. They make 2 sets (street an track) depending on the noise level you want. At VOI X the Corsa tech showed me a cutaway of their "muffler". A straight through pipe with 2 small (3/8" x 3/4") oval slots inside the pipe. The bulge that looks like a glass pack is a honeycomb of resonance chambers that removed the "nasty" harmonics that hurt our ears by sound cancellation technology. Absolutely NO restriction, unlike every actual muffler. They cost a lot, but they are worth the money. I used to build my own chambered mufflers and turbo style, but there is no chance I could build any sound cancellation technology systems, so I won't even try. It's not a muffler, it's a "sound tuner". Call jonB
