I spent weeks researching all different types of axel backs. Absolutely zero regrets with these. Love them! Loud when I want them to be, but quiet when needed (neighborhoods). Really woke up the sound of the car. Don't hesitate, but the Roush Axel Backs, I plan to do shorty headers and a Roush Cold air intake next. That seems to deepen the tone.

Arrived a day early, although I'm sure that will vary depending on where you're ordering from. Sounds amazing! If you short shift, it wont bother your average Joe but when you take it to 3k rpm, it makes the perfect growl, and anything above that has the potential for amazing backfires in 2nd and 3rd gear. I gave a 4 star review instead of 5 because it was advertised with black tips but came with chrome. Not a big deal to me but still false advertising.

Hands down best axle back for your 3.7. This or the borla atak paired with shorty headers are the closest thing you will get to a v8 in terms of sound. Only difference between these and the borlas is these drone like a mf and the borlas dont drone whatsoever, so thats the trade off in terms of price. If your like me and you’re cheap, then get these. Drone is bearable WITH the radio on. Also, word to the wise, never remove your stock cats, the rasp and drone will literally wake up your entire neighborhood and sounds like absolute rice if you do.

Just got this on May 5th. I know it's simple to install but I took it to a reputable shop since I had no access to tools. Installation was 100 bucks in Dallas texas.As far as the mufflers themselves, wow. They sound amazing. Nice, deep rumble when starting and at idle, as well as cruising speed. Floor it and the thing screams. It's awesome. Very loud. Gearheads will know it's a v6, but your average person will think its not;)

Really super loud which is exactly what my son wanted. It sounds like you are going really fast but you aren't which is what his parents want. Safe compromise.

The exhaust really steps up the performance and sound of the car, exceeded our expectations. Great product from Roush.
