Very nice RPI. Well done
+1 A certain average Joe has to be happy with those results on his 545.

Dang it Eloy! LOL! I wanted to post this up...anyways...yes the RPi does gain power. I ditched the quad system, because I wanted more power out of the V8.

Ryan, I don't know why your car is so freaking crazy with power. Lets do some Mexico runs when you are down

Trinity Autosport will be stock the 545i exhaust. Please PM me for ordering or visit my website at www.trinityautosport.com

I guess alot of peeps will be ditching the quads! RPI is one of few tuner that will dyno
their products against others. Great job RPI

skeeter you should be making more power since you have the PC tune....according to 540oh you're not but i guess we'll soon find out come monday.
Yeah but my dyno hasn't been done since the tune...My car currently without tune was 261 or 263...Beats me....

For sure Joe...We'll do a Mexico run sometime...

No you can only have a single side RPi exhaust...Dual exhaust may come in the future if they make it, but you will always get more power out of the single sided....You would have to change your diffuser to single sided again like I did...I don't regret it one bit...I'll take the power over the look any day and the exhaust sound soooo good....
