* Smooth full mandrel bends * Full stainless Borla muffler w/2.5" in/out * Easy to install at home * Can remain clamped together or welded if desired * Smooth, low-pitched tone that doesn't invite alot of attention * Less restrictive than stock system * Great value

* Aluminized pipes won't last as long as stainless * May not be loud enough for some

Review of 2.5" aluminized catback exhaust for A4 VW models (Jetta, Golf, New Beetle) with Borla muffler and visible exhaust tip (stainless versions are also available at additional cost w/Borla or Flowmaster muffler and hidden or visible tips). System shipped in 3 pieces: front section w/resonator, Borla stainless steel muffler, tailpipe. 3 clamps with integral hangers are also included. Ease of installation: Moderately easy. The most difficult part was cutting the stock system in order to remove it. TT system pieces are of high quality and fit well, although a couple of trial adjustments prior to final tightening were needed to keep system from contacting axle and underbody heat shields. Would have been easier for me if the car was on a lift; I had to do job with rear of car on jackstands. Tone was definitely louder than stock (but stock system is almost silent), but still smooth and relatively stealthy. Overall, still a quiet system while adding a few horsepower over very restrictive stock system. Also quite a few pounds lighter!

Incredible sound and performance. Does not drone like other mufflers
Remains quiet at idle and under full acceleration. Very subtle but
noticeable exhaust note. Free flowing, very smooth rev band.

Only muffler is stainless steel.

Excellent product. One of the best exhausts out there right now.
Power increase that can be felt at the wheels. High quality product
that yields a noticeable power increase. Helps even more when
you have intake and headers. Excellent product.

Tenzo exhaust - too loud and drony.

superb build quality, quiet but powerfull sound not too
boomy or intrusive, large power increase.

nothing really

I would certainly recommend it, the only improvement I
could make would be twin exit instead of single.
Still, cant be too picky!
Showed awesome gain of 32bhp over stock system on dyno!
