I would def. get an exhaust, but make sure you get the right one. 70mm or bigger with a test pipe at min. Personally I would do a PLM header with a berk 3 inch. Or don't even do the header but get a berk 3 inch. You will make good power

 

421whp, SOS stage 2, Novi 1200 blower, 3.2" pulley, Berk HFC, OEM cat-back. Anything else just makes exponentially more noise. Sure you can pick up 5-10hp, but you'll hate driving it.

 

^^^ Yes, this post is full of win.

 

i happen to really enjoy my SE single with my kit. it has that right amount of sportyness to it, and ive had many other kinds of exhaust in the past.

 

Talk to Mike (if you haven't already) from our area. He's the guy with the SOS Stage 2 on his AP2. He was running the HKS dual for awhile, then recently switched it out. If I remember correctly, he hit some limitations with the HKS Dual and switched out to make more power. He's also running the stock fuel pump which I believe he's about to replace.

Didn't know you were looking at boost too! Should be fun, good luck!

 

I'm so happy you are boosting your car. You heard my car on the dyno but I dont know if you ever heard my exhaust while cruising but the Asura is what I recommend. It is by far the quietest aftermarket exhaust I have had and thats for any car that I have owned.

 

By noise do you mean supercharger whine?

 

That's a separate issue. (The SOS kits do make a fair amount of noise themselves.) But what I was referring to is that a SC makes the engine exhaust louder. I had to take my Fujitsubo off and sell it and go back to the OEM exhaust because it had become so loud with the SC.

It's just a question of what you like in a car. By exponentially more noise, I meant that just about any aftermarket exhaust will make a lot more noise than OEM when paired with an SC. Some guys like a loud exhaust, but a lot of us hate it.

 

Yep yep, already been talking with Mike - one of the main reasons I'm looking at the SoS kit is because of him

 

Imagine skunk2 or invidia SC then
