Just curious if anyone is running the weapon r s-pipe and if you, what are your thoughts? Power gains? Ease of install? Thanks folks!

A personal friend of mine, "Chrevis" on SL, is running the WR s-pipe. Pm him for his thoughts on it. From what I remember, he said it was a pain in the a*s to install.

I am with the weapon r header. power gains would not be real noticeable b/c you still got the factory scuba tank in the exhaust. Does not sound raspy though, and looks nice. Easy install with the header, not sure on just the s-pipe.

I have it. Its a great piece... well made and easy to instal take about 45min.

The Weapon-R 'S' pipe replaces the OE 'S' pipe, it doesn't replace the scuba (main resonator/cat). However, if you were to replace the scuba with a straight pipe, you would totally fail any emissions inspection, as well as probably not sound too good !

That depends on where you go for the emissions test. I passed MD inspection with the CXR 3" exhaust installed. No cats, no scuba. They never looked under the car. They just plugged into the OBD2 port, checked for codes, found none and passed it.

It was too loud with the CXR exhaust but after some custom work by MBS, it now sounds great with no cats and no scuba. I'm running a 3" s-pipe into a 3" I/O 18" x 6" resonator tapered into a 2.5" mid-pipe and modified 2.5" TRD axle-back.

IMO the key to replacing the scuba tank is to use a large resonator and a good muffler. The CXR resonator is too small to do anything and their muffler is just a cheaply made 3" fart can.

Ah, but you see, you really didn't have an emissions inspection .

That's what MD calls it and who am I to argue?

So would I need the header to repalce the sucba or do I need to go custom to replace it? I am glad I didn't purchase the s-pipe yet because I thought that is what it did!

A header replaces the OE exhaust manifold which includes the pre-cat. If you want to replace the "scuba" (OE resonator and main cat combination), you'll need something custom.

i have the weapon r header and s-pipe along with the strup cat back. if you are to install it your self i would say life your car as high as you can. i had to use the oem jack that came with the car in a dark garage with no power lol. wasent to fun but not to hard. just make sure you you dont leave anything loose. i did and it blew out the gasket and bent my piping. had to cut and re-weld to get everything striaght again lol
