I am trying to make a decision on which cat-less bolt-on x-pipe w/resonators to buy and I have not been able to find much information that is recent. I've searched the forums and there is some good info from different people but nothing recent with some of the new products available. I've have also talked to a few performance shops to get their opinion because I live in Michigan and I am unable to see or hear many of these setups in person.
I've basically narrowed it down to two, maybe three brands but I am open to suggestions. I want a decently loud setup that is not too high pitched and not too raspy. I also want a good build and weld quality with good fitment. I've heard of some brands to stay away from, so that's why I have not considered them. Here are the brands that I've narrowed it down to: - RPi GTM - full bolt-on x-pipe, cat-less, two resonators - Macht Schnell - full bolt-on x-pipe, cat-less, two resonators (closest to Challenge Race x-pipe, from what EAS says) - Gintani - full bolt-on x-pipe, cat-less, 2 or 4 resonators options (double the price of the other two brands, not sure its worth the extra money) I would initially be pairing this with the stock (no-mod) exhaust but eventually I would be looking to buy a rear section if I wanted it louder or to sound different. These are the two I am currently considering but again, I am open to suggestions; RPi GTM Remus Race I really would like a deep, mean and loud sound. Many people have suggested the Akrapovic but to me it is just too much money for a full system and too quiet. I saw one YouTube video of the RPi with the stock exhaust on the top floor of a parking deck and it sounded like shit, totally cheap ricer fart can sound but there is no information on which version RPi that is. I read that the new GTM version with the resonators really cleaned up the sound and some of the rasp but I do not want to make a decision on that. Just to put it out there as well, I do not want to cut up my stock exhaust and buy a test pipe. I know its a good option and affordable but I rather replace the whole thing, just seems more complete to me IMO. I'm not against spending a decent amount of money but I also do not want to spend a ridiculous amount either. Any help or comments from people who have owned these, I would really appreciate it! |

The Akra is really quiet, even when fully catless
Resonators are definitely a must. With the stock rear section it should sound quite nice! But you can always get a louder exhaust if you feel the need |

The way I look at it is that you are wanting to buy some bent stainless pipe with resonators. I don't feel the need to pay a high price when they are all made from the same material and are the same size. I got the top speed quad resonated for 800$ and fitment is great. Too quiet with stock rear section so now I have a valved rear section.
Imo the money saved is better spent elsewhere on the car. The difference in sound/appearance of the rear section make sense to spend more for a look and sound you want but I say a low price xpipe is the way to go if you are going catless. All the value of a xpipe is in the cats so a catless should be alot cheaper. |

i have Active Autowerke race x-pipe (no primary or secondary cats) paired with stock muffler (couldnt justify the extra $$ of an aftermarket muffler for only a few extra ponies) its not really loud until you go above 50% throttle, i kind of like the sound it makes. At idle its slightly deeper tone. I hope this helps....
A++ on build quality and welds! |

with the 2-pipe mod, all else stock, I'm now thinking it's better to go X-pipe and not chop up my stock one... my only hesitation is that I was thinking having the stock secondaries would help minimize any smell/fumes. I've never owned a catless car, so my worry is purely around the "safety" of not having cats since I do use mine for lugging a toddler to school many mornings. Can anyone provide any input/info on what something like a quad Resonated x pipe means in terms of the fumes?

I put on a full Akrapovic system and it's amazing. Loud when I want it to be and civilized when not needed. There are some for sale here on the forums and you could pick up a good system cheaper than new. Challenge is now being made by IND distribution. They are supposed to come back out with the Challenge x pipe here soon. If I didn't do a full Evo system then Challenge was going to be my second pick. Good luck with whatever you decide.

I know the Akra is a good system and even with the used ones for sale, they are still expensive and from everything I've read it still might be a bit too quiet for me. I just don't want to spend that kind of money and not be completely happy with the sound level. Last edited by jacoby521; 02-14-2019 at 10:45 AM.. |

As far as loudness, I guess I'm not really sure. I know I want something on the louder side and that I do not want cats but I have never heard any of these is person. I live north of Detroit and there are no many E9x M3's around. So, I'll just stick with the cat less and go from there. Just don't want it to sound like shit or fall apart. |

I've heard the the Challenge X pipe and Akrapovic mufflers sounds amazing. However, exhaust sounds is purely subjective, so what sounds good to one may not to another. Plenty of You tube videos but they hardly do justice. Best of luck, but remember, if you go cheap don't expect a whole lot. Sometimes it's better to pony up the cash and get something that's worth it.

Definitely like the white better, deeper and less rasp...it would be even better if there was a full Akrapovic in there to compare both sound volume and quality.

I forgot to mention, the black Dinan fires off first then the white mach schnell, then alternating back and forth. The Dinan has 4 resonators; the Mach Schnell has only two, hence it's louder, more rasp..

There's really no benefit to going catless over HFC's at all, only negatives of smell / emissions. I'd look at the Evolve HFC x-pipe or the Challenge version as others have stated. Most full catless setups just sound like a raspy wall of noise, may as well of bought a Mustang and called it a day if thats what your looking for.
