anyone got 2 muffs midmount?

Ok, I got a few questions going on here.
1) Does anyone have pics of two mufflers midmounted?
2) Is it possible to run 2 1/4" pipe under the gas tank without scraping the pipes on everything?
3) where can I get oval tubing besides that burns stainless place?
4) what are the advantages of going with true duals over 1 bigger single?, besides better flow. sound?
Thank you for your time

yes you can run 2 2 1/4 pipes in the factory location without scraping anything look on the front page for pics of them installed

Magnaflow Cats, Magnaflow DI/DO 2 1/4"true duals with 3 1/2" stainless tips...reverse glow gauges, 7 color a-pillar gauges, 20% tint, JVC HD deck, 10" Kicker square, 400rms mono Kicker amp.

2 Borla XR-1's midmounted...3" duals. Currently dump just behind the front seats, but will have side exits with oval pipes. I don't really have a good pic of them installed. Car is up on stands now so I guess I could go and snap one if you want. The cool part is that this is my entire exhaust system right now...long tubes with 3" collectors feed into this and that's it. It's all about flow...

I mean right under the tank not through the the little passage way for the stock exhaust.

I don't think there would be enough room...too low IMO.

I know a guy that used to post here a while back that goes by StephenC. He had 2 Offset in/out 40 Series Flowmasters mid-mounted. That was BEFORE the the gas tank (they were under the rear of the tranny area). You are not going to be able to put mufflers (especially 2) "under" the gas tank. Plus you don't want mufflers that close to the tank anyways.

I used to have pictures of his setup, but they are on my old PC. He got the flows welded together so they didn't hang quite as low. Looked like a descent setup. I was going to go that route, but then found out about the DI/DO setup and went with that instead.

He did mention that he did scrape on occasion.

BTW Blown306, that peice looks NICE!!!

Why not go dual in-dual out? Dual 2.5" pipes fit fine under the tank. I think someone ran dual 3" pipes once but that would be a tough job for sure.

If you look at my car from a distance you can barely see the single mid mount muffler tucked into the center tunnel. The only way to run 2 decent sized mufflers there is put them both in the center. [that would make for little room to make a smooth bend toward the tank] Otherwise they would drag speedbumps.

You could get away with some small glasspacks or something like that. Just remember that mufflers need size to dampen noise AND flow well.

I am going to mount the mufflers under or around the tranny, I was just wondering if I could run pipe under the tank because I'm putting together the exhaust myself and it would be easier to go under the tank instead of in the little passage way. I won't have acces to a pipe bender.

Probably going catless so I figure if I go with 2 mufflers instead of 1 DI/DO I'll have a little more backpressure to keep some of my low end. BTW I'm going with Flowmaster Original 40's.

It wouldnt work out too well, IMO. Go out and lay down beside your car and look under it... and imagine a 2.25 or 2.5" pipe running under there, out of the normal location. it isnt a good picture

I just checked it out and I would definetly scrape on everything and I have to go over 4 speed bumps every time I leave or go to my house.
I mentioned this above but just incase no one saw it: I'm probably going catless but I don't want to lose any low end, so its safe to say 2 Flowmasters would give me more backpressure than just a single DI/DO right?
Thanks

I'm running a mid mount Magnaflow and two cheap turbo mufflers. The single muffler was too loud. I hate drone.
