It's my stillen exhaust. Lol..!!

Mods please and what do the lines represent (I'm guessing the dark blue is ART with a retune). Nice numbers by the way and does anyone know if the md shockwave tdx produces more hp and tq than the stillen td? I know that stillen's made the most across the board in the past.

I think that would be a good test also the only thing is the stillen doesn't sound anything like the shockwave.

I got Berk HFC's and my next step is cat back...makes me lean away from the HKS and more towards the MD...but either way i guess id like tp's but its way raspier, and not to mention illegal (not that i care) but passing emissions is always harder...how much of a difference can test pipes make over hfc's? a few whps at most?

Are there any fumes with the ART pipes. Thats my only concern. They look like they open up the car alot more than HFC. I'm pretty content with my Berk HFC for now. They do the job except i just dont like the hissing noise cause of the backpressure.

ART definitely smell at idle-just like any other test pipe

Has anyone done Berk HFC with MD shockwave exhaust? I'd like to see the dyno for that...

I am Sold i am Buying ART test Pipes...

and stillen is bang ofr the Buck i had HKS fast intentions n non of those ***** produce the power stillen X pipe true dual exhaust makes.. Now i will combined them with ART pipes =)

TP>HFC or HFC>TP ????

test pipes are less restrictive therefor they make more HP right??

Shockwave Vs Stillen X: That would make a good comparison on the dyno.

Test pipes are less restrictive and make more HP.

I would love to see that dyno, but for some reason, I think you may have see those results already.

No. I'm not aware of that comparison ever being done. But I'm always down for a good dyno comparison.

i would also love to see that

I'd like to see this as well.
