Default Re: AR20 or Status Gruppe Rasp Eliminator Pipe

Doesn’t appear that anyone actually answered the OPs question. Is the SGT rasp section 1 good pipe to achieve rasp elimination?

I have a SGT Rasp section 1, most of the rasp is gone.But not all, I also have SGT headers. When I hear the rasp , its seems like its coming from the headers. strange,,But the SGT rasp section 1 do help with rasp. With stock headers, It will help more. I also had the custom performance rtx with cats and resonators, and all the rasp was gone.

I'm likely going that route. Do i need to get the o2 bung with the SGT section 1 or am I good without. looks like its another $75 to add them

AR20 is probably both cheaper and easier to buy. If you want it now then get the AR20. If you want to wait half a year buy the SGT lol.

Default Re: AR20 or Status Gruppe Rasp Eliminator Pipe

I'm intersted in this information as well as i have the SS Race sec3 currently. I was going to go with CPI RTX, but is the $400 price tag worth it? Will installing 2 AR20's in the oem sec1 produce the same effect for much less cost? I plan on adding AP headers and SS resonated sec2 soon also.
If there is a performance reason, or will the RTX will reduce the rasp more? If not, I can't see the justification for paying $300 more for the RTX for the same results.

Don't go with CPI RTX. Bimmer world bought them out and are apparently having the system redesigned by Magnaflow. They're still working on the design/engineering so they don't even have any to ship. I ordered SGT today for $370 shipped from urotuning.com. They were already closed when I placed my order. I'm going to call tomorrow to confirm the availability. If they don't have any unstuck, then i will get refund and by AR20

I had to. Didn't want to ask the question again in another thread but they never addressed it when asked here as they got completely side tracked.

Ar20’s are faster to get and is guaranteed fitment if welded on by reputable welder. Oh and it’s cheap as hell, since you only really need one next to the factory resonator.

good point. I don't want anything magnaflow, or anything unproven on my car.
Since CPI has been effectively killed by bimmerworld i think i'll just stick with AR20's. I'm gonna get two and replace the OEM resonator since i'll be going with headers in the near future.
