Looking for shop in Southern California, preferably in Los Angeles area, that can modify exhaust system to add more roar to the car's sound. 2001 MR2. Would appreciate recommendations.

When I got my first Mr2 (a 2000), I loved the car but hated the exhaust sound. If I closed my eyes, I could swear I was listening to a Corolla running. After a lot of looking at options, I bought an exhaust similar to this one on ebay and installed it myself: http://www.ebay.com/itm/3-DUAL-MUFF...MRS-MR2-SPYDER-W30-/150723518277?hash=item2317d25f45:g:I1gAAOSwyTZUWUIK&vxp=mtr

The rear bumper has to be removed (write up available on this site) and it is pretty much a bolt on. I like the sound much better - not overly loud, but definitely deeper with a bit of a raspy sound. I did notch my rear bumper to accommodate it - with some work you may be able to install it without cutting the bumper so you could easily go back to stock if you want.

Mike's Muffler in El Monte, CA.

Built me a Mandrel-bent (mild steel) system with a magnaflow I selected for MUCH cheaper than any of the big name (HKS/Greddy/etc...) exhausts.

looks good and sounds great!

I personally wouldn't touch any of the Manzo or similar $200 exhausts, the quality just isn't there for the muffler itself and many are known to spew out fiberglass insulation on startup, and then start to rattle after a year or two. I went with a known quality (Magnaflow) muffler for this reason. In CA we don't need to worry much about rust, but some exhaust paint will be enough to keep surface rust at bay.

Ditto on the Magnaflow solution. I used a Che muffler on my Spyder and while it sounded great, the fitment was not good. It rattled against the frame rail, so I bent it a bit, then it rattled against the cat, so I hammered the cat heat shield in a bit, then it rattled against the bumper cover, and then my engine blew and I sold the car before I figured out how to get rid of that rattle.

I got a 4x9 Magnaflow 11236 for my FR-S for 60 dollars, and had it welded in for only 70-80 dollars IIRC. It's very light, and almost stock quiet on the FR-S, which sounds pretty crappy no matter what you put on it, but it lets a nice clean growl through. The Magnaflows seem to have very little restriction while reducing the sound a lot, if you read some comparisons, and doing it this way is cheaper than buying a whole catback for the same amount of money then spending a bunch of time trying to put it on.
