Alternative to GMMG? I was looking on CHP's website and saw where Ricks First Generation is making a chambered cat back for the late model f cars. From the pictures I could see it looked basically the same as the gmmg but I think it had an extra chambered section in the ipipe. Its $599 for a completly stainless system and $429 for aluminized. Anybody ever seen one of these?

Re: Alternative to GMMG? Just curious if anyone knows if he has done any dyno testing. I know Matt(GMMG) spent ALOT of time making sure our setup was not only the best sounding but also one of the most power making catbacks there is. He went through several designs before settling on what we have now.One curve in the wrong place or an extra chamber can rob power. Just an FYI guys. Goodluck

Re: Alternative to GMMG? I still think the price of the GMMG is rediculous and he's making a killing off of it. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> That said, the only difference that there could possibly be between this setup and the GMMG is the construction of the chambered tubing. The rest of it is mandrel bent so that's not even an issue.

Re: Alternative to GMMG? Sorry about the lack of a link guys. I forgot to put it in there before I went to work. Honestly I dont see how there could be that much difference int the two. They both have the same design, mandrel bends, looks to be the same size chambered sections. I dont see the chambered sections flowing any different. Theyre all made the same and have been for the last 40 years. The only thing that bothers me is from what I could get out of the article there is a third chambered section in the I pipe.
Re: Alternative to GMMG? Sounds like too many chambers to me. The GMMG I'm sure flows better, less chambers. Let's look at this for a second GMMG specializes in the NEW F-BODIES, and Chris doesn't. GMMG gets contracts to make BLACK BIRDS and ZL-1 camaros, and Chris doesn't. I'd put my money in GMMG. Sometimes, experience speaks for itself. <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" />
Re: Alternative to GMMG? So if you got a straight 3in pipe welded in place of the 3rd chamber for $20 it be the exact same thing as the $700 GMMG exhaust? I really don't think chambered pipe can be that much different. I can assure you that the cost to make the chambered sections isn't as costly as a full sized muffler, like other cat backs have. I'd really like to see someone have a comparable product to the GMMG for half the cost.

Re: Alternative to GMMG? Fast, thats exactly what I was thinking. Get rid of that extra chamber and its the same as the GMMG. You might even be able to get in touch with these guys and have them do this at their shop. Might actualy cost less without that chamber. Honestly I still dont think it could be that much difference even with the chamber in there. A cat-back doesnt make all that much more over the stock exhaust anyway. Ill gladly save $270 even if I dont have the extra 3 hp the gmmg might give you. $270 is over half way to having jet hot long tubes. BTW Nolatrans, if you look at their website their actualy pretty involved with fourth gens. Theyve got quite a few project cars including a rare 30th annv. LT4 SS

Re: Alternative to GMMG? I don't know where you get the $270 price difference, I payed $650 for my GMMG, $50 more SHIPPED. Not to mention that the system came welded, with only 1 clamp needed to put it together, unlike the multiple clamps in the other system. Add the extra 3 inch tubing to ditch the middle chamber and you are even, and it will cost more than you say to find a 3 inch section of Stainless pipe You get what you pay for.
Re: Alternative to GMMG? I agree with Cammin BeaSSt, I have listened to Matt from GMMG talk for hours about the testing on every part he puts on his cars, so I never even considered any other exhaust. I am certainly not rich, and as a matter of fact the GMMG chambered is the only mod I have done to my SS. IMO nothing compares to the GMMG.
Re: Alternative to GMMG? I think he got the savings from using the aluminized version that's only $429. Add in the price of a straight aluminized pipe welded in for ($20) and the total comes to $450.
I can see why a lot of people stand behind GMMG, but I'd really like to see the difference in his chambered tubing compared to this, or even the kind you can get for dirt cheap?
I remember when the Borla exhaust($700-800) first came out and how everyone raved about how great it was with the open plate. Then about a month later everyone was doing the Zed style cutout that was escentially the same thing for $30. Sure the Borla looks better, but some of us are more concerned with functionality. If this new chambered exhaust can flow as well as the GMMG, I'd say it's better since it's a lot cheaper. Aluminzed is fine for a lot of us. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Alternative to GMMG? Seems like a nice system although the stainless one(which IS important to a lot of us) is almost as expensive as the GMMG(also stainless) system. And the GMMG price includes shipping.
I also heard before that the older version of the GMMG exhaust had a third chamber in the intermediate pipe(which supposedly effected flow). I don't see what the third chamber does(sound?).
At least someone else is trying to come up with another chambered exhaust although this one seems very similar. The aluminized could be a good deal though.

Re: Alternative to GMMG? Yea I was talking about the aluminized vs the gmmg. I swap cars/exhaust enough to where stainless really doesnt benefit me any. I also dont have to worry about salt on the roads so an aluminized system will last as long as I need it too. Not sure where you got multiple clamps from. The rear chambered section bolts to the I-pipe the the tailpipes are clamped on. I would think the extra chamber is there to quiet the exhaust a bit. I read an article in camaro performers about the ZL1 prototype. Some of the magazine staff that drove the car complained about excessive exhaust noise inside the car with the gmmg.
