All, the exhausts mentioned are reasonable choices, the SMSP setup is great, but very spendy.. Personally, I dig the Buddy Club line up. The fit and finish on all of their parts are top notch, and they keep everything light weight. Their pricing is also very reasonable.

Here is the Spec IV. It is one of the more *quiet* exhaust. But still has an efficient design.



Here is the Pro-Spec. It's slightly louder than the Spec IV, but also has a removable silencer.



Here is the Spec III. This is the louder than all the aforementioned exhausts, but is designed to be very lightweight, it has very few bends to make it very efficient.



There is also a SpecII (not shown) which is basically a test pipe w/one resonator.. It is uber-loud This setup is very affordable ie sub $400 range. I may be getting this for my own vehicle shortly.

We carry the full BC line up here, so if you interested in any of these exhausts or other products drop me a IM and I can get you discounted pricing.
