RPi Limited Edition ST section 1

Its back my friends. After much demand, we have made a limited amount of our ST section 1 with high flow race cats. Please call to order while they last. This part is a direct bolt on for our system and could be made to fit the stock exhaust using our exhaust adaptor kit.

M5board price: $995 (regular $1120)

Unfortunately, no. This section is longer than the M6 front pipe so it will hit that intersection. The only thing we have for the M6 are the catless pipes.

Hi Eloy!

If you don't mind the question, may I ask which cats you have used.

Thanks
Hasan

I'm confused....Can you clarify all the options and the differences between them?

I thought the options were:

1) GT section 1 (just straight pipes) Loudest option *

2) GTS Section 1 with resonators - more quiet option *

*Both option 1 & 2 have the same section 2 & section 3

what is the ST option?

What do you mean? We had custom 200 cell race cats made for us.

The ST was a limited option we did in few years ago. The ST came with cats in section 1 instead of straight (GT) or resonators (GTS)

Interesting...so you only replaced the stock exhaust with RPI section 1-3 and there is a noticeable smell?? I thought the smell only became apparent with headers.
