helix here. like everyone says great quality for little cash, few bends, sounds mean as **** at wot. glad i decided on the helix.

 

good experience with perrin exhaust, great sound (not to loud)and good response. Fits perfect, easy installation.

 

The only exhaust we have a problem with is the Helix unit since it is low hanging and angled in such a way that it burns our dyno straps

Check out our exhaust. We were just involved in an exhaust shootout and were the top performing stainless steel system in the shootout. We were also the lowest price system. The other system that did outperform us did it by .8 horsepower and 1.3 ft lbs of torque. After peak torque was hit though we made more to the end of the pull. Difference in cost between theirs and ours was $800 for the catback alone.
