hey, im about to get my chambered exhaust, need to know if it comes with the intermediate pipe and over axle pipe, thanks

 

Yep.


Nice user name too. Fellow aviation nut

 

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.

 

yea.. i love aviation stuff, actually im in the army though, im an apache crewchief. thanks for the info too

 

pics???

 

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 dont know if anyone else with a cut-out has noticed, but in some cases its actually slower than running a good muffler, you lose alot of back pressure with it, i closed my cutout today and it felt like a noticeable low end horsepower gain, but then again my car might be one of those cases since i have no cats.

 

i'm running a flowmaster 3 in catback with stock tips..

 

Something is really wrong with that. Seems like thats what everyone is saying. Is the Camaro the only car in the world that loses hp with a cutout? There has to be more to it than that. 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.

 

It's not hp... You actually gain a horse or two, but lose a handful of torque.

 

I understand that but lots of people are saying opening it made them go way lean or rich (threw off their tune).

 

^^^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.

 

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.

 

What difference did it show with the power numbers?
