Been on here since I got the RevUp new, but rarely post. Doing so now to just help push those that are even close to considering the ART pipes from Motordyne. I have Nismo headers and previously Berk metallic HFCs, JIC Y-pipe and the rest Nismo exhaust. The exhaust was done in stages but when all done the car dynoed with 272 WHP on a DD and I was quite content with the power of the car. The HFCs made an annoying rasp at 3500 rpm but it was gone by 4200 rpm and only when punching it, so not that bad. Then the rasp started to get louder and the duration over rpm band got larger. Then I heard the the driver's side cat fail. I started reading on here as to what new HFCs to go with as never liked the sound of TPs. Yhen saw what everyone said about the ART pipes and thought if it just quieted a little bit It would be an improvement.

Moving forward got them in the mail a week ago and first thing I noticed was the appendage for brace attachment. Did not realize they were doing that. Anyway got them installed and must say as advertised all rasp is gone and car sounds great. It's only a little louder than when I just had the Nismo exhaust with stock cast but much deeper. So if you are tired of brash loud raspy exhaust these are great. Don't know whether lost or gained power as it feels the same as far as acceleration but all the rest is great. I could actually show up late to work without everyone in the building knowing i was late.

Great Product and worth the cost!

 

If I ever need to replace my test pipes these are what I plan on going with. But without any reason to believe my test pipes will need replacing (Berk non-resonated), I doubt that'll ever happen though. I get some rasp in the mid rev range under WOT but other than that it sounds fine to me. Good to know these ART pipes are out there though.

 

yes ART pipes are the shizzzooo

I do like a tiny bit of raspyness from an exhaust.
