ART vs TP
 

I have an Invidia Gemini catback and loved the tone of it, just wanted it to be a little bit louder and obviously wanted more power... so I bought some invidia test pipes and got it installed the other day. I love the volume when I step on it BUT the drone at 2k rpm is pretty bad. The tone of the exhaust also took a hit, louder and deeper but also not as refined, fairly more raspy. Does anyone have a comparison video with ART vs TP? I'm wondering if the ART will be noticeably quieter, and wondering how the drone is as well... Also wondering if there will be a power difference between the two? I paid $200 for the TP, and $80 for the install... Will have to pay another $80 to swap it out for the ART and probably won't be able to sell the TP for very much :( So big loss in money if I were to switch, but if it sounds more refined, has no drone and also keeps the power gains then I wouldn't mind doing it. There was definitely a noticeable difference in power after installing the test pipes so the last thing I want to do is put the stock cats back in haha. All help is appreciated!

I don't think you would have a hard time selling your Test Pipes on here with low mileage if you end up swapping them out...

I am about to make the switch to TP myself, but am on the fence on whether to go RTP since I added the 18" resonators to the FI exhaust I ordered.

Just a thought, but why not get some high flow cats. Should help with sound and drone.

What Newtoz said... I have the Invidia Gemini with the Fast Intentions high flow cats and I LOVE my exhaust sound. The tone is great, it's loud but not obnoxious, and theres practically no drone/rasp.

Running art plus invidia for approx 500 miles. When first installed there was a hiss on decel, that has significantly gone away. As for drone/rasp, no drone, very little and I mean little rasp (cant stop it completely running any kind of non-res pipes). The invida was rumored to have the smallest drone/rasp when combined with tp/art pipes, this has been true in my experience, 2600-3200 rpm, you would think it was stock.

Ahh really? If that's the case I just might swap them out... it's only been on for 2 days lol
I wanted TP over HFC for the gains and price lol, but I guess the price I pay for labour + buying another TP/ARTP would be around the same as going HFC in the first place..
Ahhh really? I don't mind the hiss at all, though it's really noticeable through accel and decel right now all through out the RPM range if I go WOT lol. It's just the drone and the slight rasp that bugs me a bit. It reminds me of my friend's HKS catback + Berk HFC, which I really don't like because of the raspy sound. Actually right now at 2600-3200rpm my non res tp do not drone at all either, it's just right by 2k (give or take 200rpm) where the drone is annoying. Do you notice loud drone at that RPM as well?
And yes I was happy to find that Invidia Gemini was said to have the least amount of rasp/drone haha, I lucked out there :P
