Buy it, I have a A3 racing, mine no need resonator, but cost me w\ the instalation $150.00 I have it for 2 year now. I love the sound. You will love the new look and sound.
I got a borla muffler. It's a very solid, yet straight thru design that produces a loud deep tone. All together my exhaust cost me a total of around $350. That include all new 2.5" piping from the front pipe back, muffler, high flow cat, and tip.
Well I will pay like 100.00 to 130.00 more to remove resonator and put a hi flow catalitic. And like 140.00 for a custom header. But I will chk in another muffler shop here. Is in midle of no where but the guy is a master in this stuff and the prices are lower.
more or less, I will go next week and ask for the header. This will be thursday. But firs do you have a hi flow catalitic? and a hi flow exhaust? and do you already remove theresonator? Do this before....
