Default Equal-length header sounds

First sounds from our prototype exhaust with PPE long-tube equal-length headers.

Sounds great Mike!

So this isn't with the PPE rear? Doesn't look like it just confirming.

No this is our dual to single to dual setup. First pass.

Sounds great. PPE is installing my shorties with their exhaust the week of the 5th. This has me super excited to hear what that combo may sound like.

Sweet! Are you getting the PPE dual? Curious to hear the sound with the EL. I'm on the fence about that or the long tubes but the extra exhaust modifications I'm not trilled about.

Sorry I should've quoted the above quote it was meant for him. For some reason I thought he said Unequal length shorties, but now realizing he is doing the RCF equal length shorties modified for the smaller flange outlet for the ISF


I also realize the long tubes were equal length just with an added 12" to the equal length RCF headers

That's correct. It'll be the EL shorties and the dual mode PPE exhaust. I wanted to be able to keep the exhaust noise down as much as possible so to not **** off my neighbors, but loud when I want it. Paul will be getting a baseline first then installing the headers and then doing another dyno. I believe they may be doing another dyno after the exhaust is installed, but i'm not sure. Either way we'll have #s for before/after on the headers.

Sorry to detract from the post here. Back on topic, it's going to be nice to have another exhaust option for the ISF and this one sounds amazing with the headers. If I were still on the market for an exhaust i'd definitely be interested in this, but there is a lot more info yet to come on them. Either way i'm eagerly awaiting more updates.
