I don't regret anything yet....but won't really know until after I have more stuff installed.
My current exhaust is:
Factory Stock Headers
RandtomTech Ceramic High-Flow Cats
Corsa 3" Cat-back Exhaust
I just bought new ARH, so my Exhaust setup this summer will be:
American Racing Headers 1-5/8" X 1-3/4" Step Design
200 cell ultra high flow metallic substrate cats
Corsa 3" Cat-back Exhaust
I should be pretty happy with my new exhaust setup. I will feel a little more power out of the car while seeing higher numbers on the dyno.. and my exhaust should sound pretty good along with it being A LOT louder which I'm looking forward to too. However, if I'm not happy with my new setup..
whether I'm not crazy about the sound or I think it's too loud(Which I know I wont, since I want it to be loud.) or if it happens to worry me a lot regarding the Stainless Steel Headers heating up too much(Although I've heard this really isn't a problem as most people claim it to be, so I'm not really worried about it.) then I might consider changing out the whole exhaust next year.
I do like the sound the Belangers make, and they seem to be good for performance gains too, but at this very moment if I had to choose another exhaust setup besides what my car will have this summer.. I think I would go with the following:
B&B headers
B&B Catback
High Flows
X-pipe
Heard a video of this setup and absolutely love the sound. I will of course post a sound-clip of my new setup once everything is installed. Should sound amazing
