That was me. I had been searching for the perfect exhaust since 3 years ago. The options were few. (Comptech, RM, RSR, DC Sports, HKS, Finstar, ARC) Then I heard the GruppeM a few months ago and was very impress with the sound quality. Then SOS offers the Taitec at 37% of the GM's price.
I purchased the Taitec based on the feedback from others, I was excited to get the Taitec. The built quality was very high. After the install, I was impress with the sound level. Quiet below 3k RPM and good sound level at WOT. Regardless of the built quality of the unit, there is no comparison to the GM setup. Compromising just was not an option. The GM built quality is also very high. I just love that dual canister design.
On top of that, it weights 35lb(?) that replaces the OEM exhaust (45lbs?) PLUS both CATS (30 lbs?). It connects directly to my DC headers. Just love that setup!
There are a couple of things that I have to live with though.
1>The dual tips misaligned by 2/10th of an inch that comes very close to the valance on the right side.
2> From 3k to 4k, there is a slight booming sound in the cabin when you open the windows. It is more noticable on service streets driving. Highway driving is perfect though.
Other than that, it is exactly what I was look for. To justify the cost of the unit, it is like shopping for speakers of a stereo. They make all the difference of a stereo. All in all, it IS the right exhaust for me.
