Sport Exhaust

[AsianGuy98]

Anyone know if the Sport's axleback will fit the Si? I like the Sport's a lot better than the Si's, I bought an Si because of the options it has instead of the Sport. Thanks in advance.

I would like to know this too.. Also does it sound a little bit louder?

I'd be very surprised if the sport exhaust is louder, it's pretty quiet.

I highly doubt it. The wheel base is the same across all platforms, but most likely the exhaust section is a different length or the bumper overhang is different.. The both exhausts are one piece from the down pipe (post cat) all the way back, so there isn't an axle back per say, meaning you'll have to replace the entire piece. Hangars at the muffler point could be different as well, but since it's a center exit like the Si, then I would suspect it's the same. The Si exhaust definitely looks to have a bigger diameter based on the pictures.

Hatch sport part number: 18307-TGG-326
Si coupe part number: 18307-TBJ-A03
Si sedan part number: 18307-TBF-A03

This is the hatch sport exhaust:

From what I see in the drawing, and what I see on my car, you should be able to cut the pipes behind the "megaphone". That way you can keep the factory "high flow" exhaust. There won't be enough room to screw on extenders. Your going to have to take it to a muffler shop and see what they can do about separating and welding.

The Sport exhaust tips looks a lot better IMO

I'm interested in seeing if someone will do a "Gundo" exhaust hack on the Sport/ Si mufflers. It consists of welding a mini pipe from before the muffler to the tip to allow 30-70% (depending on pipe diameter you use) of the exhaust to bypass the muffler. So you get added sounds (usually end up being throaty and choppy) under hard revs and accelerate but no cabin drone and the car is still quite like factory when crusing/ driving normal.

Very popular on Honda S2000s, Corvettes, Porsche and BMWs.

Is there any loss or gain from doing this?

More than likely non other than the sound difference. If there are any gains to be had or lost they would be negligible as I haven't seen anyone talk about them or any dynocharts of before and after.

This exhaust on the SI gives it the Hatchback center outlet look. Just wait for this one or I'm sure even all the other exhaust's in the works for the SI will have dual tip in the center
