GB: Supersprint Exhaust Systems Part 2 by MpowerMotorsports

[R717]

Section 2 isn't exactly needed. It is if you are complete FBO (CSL airbox, cams, exhausts) as Obioban pointed out in his development of this section 2 with Supersprint

Double-checking before I pull the trigger - the 63.5 mm hjs catted sec 1 will bolt up to the stock sec 2?

[Epoustouflant]

Ok, that was my question. The 63.5mm headers are only compatible with the new 63.5mm section 1, the SuperSprint HJS cats I currently have on the vehicle are apparently 60mm?

So it sounds like the V2 stepped headers aren't on the table with this offering and I'd need to order both the headers and a new section 1, as well as a new section 2 to see the benefit of the 63.5mm.

thanks

Are the prices for the catted sport and race kits backward? Catless race kit costs more than catless sport kit, but catted sport kit costs more than catted race kit. And individually the sport muffler is cheaper than the race muffler. Am I missing something or is it not adding up?

The race rear section is more expensive than the sport on the catless kits.

The catted sport kit is indeed missing the 5% package discount, good catch. I can apply the discount after the order as I can't modify the live listing,

good catch.

The 63.5mm headers are really only compatible with Supersprint's Section 1. You have 3 options - from expensive to affordable: HJS catted, Resonated Catless, Catless.

Didn't plan on getting an exhaust yet but thanks for setting the GB up, I'm not going to pass this up.
I have 1 question though. I like the 63.5 stepped header into the 63.5 catted sec1. Section 2 twin pipe shows it's 63.5 also, will this bolt up to the stock muffler or a muffler of my choice?

Thanks

Yes! Supersprint designed it to fit any rear section that used the OEM mounting points / pipe routing.

Any update on this? The new price list just makes this even more enticing.

Not yet Abdul will ask tonight and we'll have an answer tomorrow (hopefully).

I will know tomorrow.

I'm pretty sure it's the same as all standard style headers which are 55mm outlets (2.16") The 60mm (2.36") reference is, I believe, the OD of the SS sect 1 that slips over as well as other aftermarket brands. The stock sect 1 starts out at like 58mm I think and increases slightly to 60mm at the sect 2 joint.

I took my measurements back in like 2016/2017 so memory might be fuzzy, but when you see 60mm that's an aftermarket product meant as replacement for the stock pipes and 63.5mm is Supersprint "oversized."

I know what I've written is pedantic, but the point is, if you're comparing flow, 63.5mm to 60mm is different than 63.5mm to 55mm.

The slip fit end of the oversized sect 1 (v1 stepped) is actually 66.5mm to go over the 63.5 ends of the v1 stepped headers. It all adds up.

What's the SS part # for the v2 stepped?

Neverminded, it's 044901, so the SS v2 stepped is 60mm with as stated, 2-bot flange.

You can get the v2 stepped (they connect to stock style sect 1 flanges unlike v1s). You'll only be giving up about 5-10hp to the full stepped 2.5" version.

Are there any options that make sense for someone who currently runs a SS catted section 1, the flanged version, SS section 2 single unresonated to incorporate the stepped headers? Or do I need to order headers, a new sec 1?

The traditional Y pipe ("X" pipe) SS sect 2 will also help eliminate rasp, but with the advent of the 2.5" twin tube that actually makes legit power, the midrange robbing Y pipe is irrelevant unless the cost difference were enough to sway you.
