New to the forums, just bought my second S2000. Has an HKS exhaust and a Comptech supercharger on it professionally installed by a specialty shop in LA. Mostly picked it up because it has 19K miles and they have all the dyno paperwork on the install. Not happy with how loud the exhaust is, so looking to purchase or trade for a low miles OEM exhaust.

-Also wondering if that will mess with the tune since it has the supercharger tuned for that exhaust.

Any other feedback or ideas would be appreciated!

 

The stock exhaust flows well with a supercharger, comparable to the HKS you have on the car assuming its a dual, so no its not going to effect the tune much at all. If anything will be slightly richer/safer.

I have a stock ap1 cat back for sale, but its just not reasonable to pack up and ship unfortunately.

 

Where are you located and is it an AP1 or an AP2?

 

Thanks for the info Junky, I'm in southern California in Santa Barbara. its an AP2 2004.
