Gmmg chambered owners, quick question
Re: Gmmg chambered owners, quick question
I can't see how GMMG can be worth the money. I got an e-cutout and chrome oval tips (identical to GMMG tips) for less than half the cost of GMMG catback. Probably similar power gains/loudness. Just my opinion.

Re: Gmmg chambered owners, quick question
It's not about loudness. If it was all about loudness everyone would just run a cutout and be done with it. It more about a certain sound quality that sets it apart from other sounds. Now is the GMMG worth it? Heck no. There is no way I'd pay that much for a muffler unless it's made of titanium or something. But to each there own. I'm going to do my own thing with a sweet flow or powerstick and save $700.

i don't have any, but I got the tips from Canadian Tire (which you probably don't have) for $100 Canadian. They are "r-active" DIY tips.....whatever that means. But they are basically the same as GMMG tips.

I think the WB in the exhaust at the dyno is thrown off when the cat is open for some reason. There has to be more to it.
Re: Gmmg chambered owners, quick question
^^^While i was on the dyno i did back to back runs, one with it open and one with i close and it did nothing for my A/F ratio. I thought i might because the engine was breathing better, cause i was still runjning through the stock catback, but it didnt.
Re: Gmmg chambered owners, quick question
Yes, it comes with everything you need....all pipes, even band type stainless steel clamps. Even comes with directions for the less mechanically inclined individuals. The quality of the GMMG system is excellent, requiring no "tweaks" for proper fit. The sound is second to none. There are many systems that are just plain loud, but the GMMG chambered system has a nice deep tone with no raspyness.
