Ah, I remember you now!

Back to what Frank said... the Dr. Gas ovalized tubing is really nice but spendy. I wish I would have done it on my car. I do run a Dr. Gas X-pipe though and the quality is excellent, especially the siamesed transition, it is much smoother and more well matched than any other brand I've seen.

However, my experiences with Spintech mufflers haven't been so good. Their fab quality seems a bit lacking (i.e. poor looking case welds) and I now have 3 friends who have all had baffles come loose inside the mufflers in under a year and start rattling. They were all replaced by the installing shop who is a Spintech dealer under warranty.

They do sound mean though, spintechs have a unique and very deep and rumbling without the hollow "ping" of 2-chamber flowmasters. They also have much less interior resonance than Flowmasters. I like how they sound on my friends cars but they're too loud for my tastes though so they're not on my car. In the end I still prefer a straight through style muffler like Borla, Magnaflow, Straightline Performance, Dynomax Ultraflo, etc. Just about all are quieter and have less interior noise than the Spintechs.
