Review of RPi GT Exhaust

Simon@RENNSpec · 03-09-2009, 12:58 AM

Drove Josh's car with the RPi system on Saturday...Huge difference from stock, throttle response is much quicker and the quality is amazing. Little raspy but overall I still the like the sound.

Eloy, it was great meeting you at the Vorsteiner meet! I am planning to stop by at our facility sometime this month, please PM your email address!

In the three runs, the full system didn't seem as loud as the cat back. Is that the case?

I heard a hint of rasp on Josh's car at the Vorsteiner meet, but there's nothing in the vids. Maybe it only happnes when the car is just reving and not when it's under load?

The full system is louder, it's deeper and resonates more.

Thanks!

RPI...is there an option for those of us that can't/don't want to lose our cats for inspection purposes...? aside from just doing the muffler section?

BMWDEMON · 03-09-2009, 09:05 AM

Please let me know when the exhausts will be ready again for the E90 M3....I am really seriously considering this system and need it for May.

When are you coming back in to install the rest of the exhaust?

everyone was saying that these was a cheaper exhaust based on the price point, but the aa exhaust is coming in at 2695.00. am i missing something?

The $2695 at AA is for the rear section only. RPI's price is for a system that replaces the entire exhaust from the headers back.

As Fstop mentionned above,

The AA is only for the muffler section . The Xpipe is another almost 2k for a total of about $4500. BIG difference over RPI and AA price.

$1707 for the axle back + $1224 for front and mid pipes = $2931 if bought piecemeal.

$2637.90 = packaged deal

I got my full GT exhaust installed, along with the scoops on Saturday. Thanks Eloy, and Joe, the exhaust is sick.

I'll post my review, observations, and also the dyno from the pre and post install.

Here's the link to the dyno.

Sorry, there are no plans for any high flow cats.

I think the exhaust will fit on the E90 with no problem. We had one here and the only difference was the tips. With the full exhaust, there is enough room for our adjustment that it will line up just right. If there is a local E90 customer that wants the exhaust, please give us a call and we can work out special pricing for the FIRST person to schedule.

Good to see you again. Hopefully the wife is ok with the added sound.

Surprisingly she likes it. She was afraid that it was going to be like my SuperSprint Cat Back setup on the E46 M3 where it droned like a mofo.

The Full GT doesn't drone much at all.

Toys like these make the car even more fun.

I was just pulling your leg

but I'm glad you love the exhaust.

By far the best system out for the M3 so far.. Everyone at the VRS meet will probably agree.
