RPI vs MRF

Currently I have got a test pipe and secondary cat delete on my car. Thinking about putting a full exhaust system on my car and I am stuck between those two and couldn't find a comparison thread.

I was leaning more towards the MRF exhaust since I was reading about Malek's car with its performance gains but a friend recommended the RPI exhaust and says that the performance gains are awesome and he loves everything about it.

Those are the only 2 exhaust that I would consider and would like to have both without any cats, so, emissions is not an issue here.

I am currently punching out 371whp and would LOVE to get that 400whp which would make a super happy man!!

Would appreciate anyone chiming in about those 2 exhaust and maybe share some power gains and daily drivability etc..

MRF does not produce a catless X-pipe anymore and they are super hard to come by, basically they are known as the unicorn of x-pipe's

You're very welcome! btw the closest x-pipe to MRF would be the Gintani X-pipe, it also had the x cross sections moved up and is said to be the reason why these x-pipes make more power than others. RPI is super high quality as well so you can't really good wrong

ESS Tuning has the x section moved forward as well. I have a quad resonated ESS xpipe for sale if any body is interested. I will only ship to the lower 48.

That's true forgot ESS came out with an x-pipe

You might want to reach out to Malek before making a purchase.
