Invidia, helix, perrin, cobb, maddad are all good downpipes. What is your budget, catted or non?...

All bellmouth downpipes will probaby sound and perform about the same. The only difference will be whether or not you want it catted.
Just don't buy the HKS, it doesn't have a bellmouth design, and has the stock bends.

I have a catless invidia and I love it. Great fit and finish.

BTW- Do you already have a catback? If not, that will probably be where you get the biggest sound difference once doing the downpipe. If you're just throwing a downpipe on the stock catback, then the sound difference will be very minimal. I have that invidia downpipe on my stock catback, and could hardly hear any sound difference at all over the stock setup.

Also watch out for the Helix catted DP the fitment isnt the best mine was really hitting the tranny crossmember and giving me crazy vibration at like 2900-3100rpm.. I did the Cusco motor mounts and tranny mounts and it pretty much went away but still a few vibes here and there.. I would go for the Invidia, Turbo XS, Cobb if you want. Really depends on the exhaust you want to go with and if you want catted or non.. Need more info dude chime in so we know ..
