My car had already been equipped with SLP dual dual exhaust when I purchased it. I'm planning on installing another catback soon. most likely it's going to be the Borla Adjustable. Will there be a noticable hp gain? and also. will it be a lot louder? It's virtually impossible to tell via watching videos.

Also, it's an 00' M6

Thanks!

 

going from that exhaust to basically a cutout...assuming you run the borla with the "wide open" plate...you'll maybe see 5-10hp.

and it will be alot louder and raspier

i would stick with the D/D and just install a $40 cutout

 

I like the Dynomax Ultraflow with the straight-through design.

First off, thanks for you responses.

The reason I plan on changing out catbacks is because my D/D has shown increasing signs of rust. On initial inspection right after purchase, My brother and I discovered the pipe that goes over the axle, has over the years banged and has almost rusted through. I believe this is due to the car's life basically sticking around New England (NH now.)

I've listen to pretty much every clip on ls1sounds.com. So, I figured it would be a worthwile investment ($3xx.xx more than just replacing my existing D/D) to go with Borla

Mike - What is this Dynomax Ultraflow system? And do you know of any good websites that sell it? My local exhaust shop only deals Borla, Corsa, Flowmaster and Magnaflow.

Also P.S I'm not much of a cut-out guy. I'd rather have a nice sounding catback.

the borla is basically a cutout...or it can be.

i think the pipes for the GMMG are stainless...and its similar price to the borla i think.

Right, that was second on the list for me aside from borla. The main thing that's selling my on that is my exhaust shop already has the adj in stock and he said he'd install it - total for $800. Otherwise, it's 700 for GMMG plus tips, plus install. unless I build up the drive to do it myself.

The one mistake I made was asking to look at it. Now I can't get it off my mind. Ohh boy.

Get the Borla. You'll like it and have something decent if you decide to go with headers or an ORYP in the future. There were like 6 vids of my '99 at LS1sounds.com (the figure-8 was one of them) that had the Borla with both cats and an ORYP. I loved that setup and would definitely recommend it to anyone.

You know what's funny about that?

The first day I had my car, my brother showed me ls1sounds.com. I downloaded ALL of your videos and still watch them all, almost on a daily basis. So, because of your car and video's, Borla has been pretty much a part of my "dream setup".

I love the way it sounds. the best is when you're rolling in after the figure 8. Sounds ultra low and burbly. And also sounds super nasty on your 25mph 1st gear punch.

I don't know if you could tell, but I believe the figure 8 was with cats and the 25mph punch was without. It definitely made a difference in the sound in person.

 

The Ultraflow is just mufflers, not a system. You can get any reputable exhaut shop to run a 3" pipe and weld on a 3" Dynomax Ultraflow. That's what I'm running here in my Camaro Vid, but that's a 4" Ultraflow and 4" Mufflex with Hooker LTs.

For the price of the Borla or GMMG why not get the Bassani true dual catback for the same price and make more power?

 

I have the Borla and I like it. It CAN be loud and raspy. Depending if you have cats or not. I am debating about going from the Borla w/ no plate to a GMMG... I've also been dancing around the idea of having a true dual setup fabbed. I'm looking to go louder.

If you have the money for the Borla go W/ GMMG. I've heard nothing but good about it. And the pipes are stainless...

IMO, Borla has more of a high pitched tone. I've heard it from outside and it sounds great tho... Just weird from inside the car.

 

The other option would be to go with some Pacesetters and true duals. For about the same price of a brand new Borla or GMMG, you can be done with your exhaust.

 

Right. There are issues though. can you have something like the TSP true dual with tips? I'm not sure Dumps are legal in N.H.

Also, I've heard people argue that you'd be better off getting stainless headers. And since I live in a state where they decide to make the streets almost look like beaches in the winter (we're salt/sand crazy)...I don't want to buy headers that won't last more than a few seasons.

I agree on the Borla vs. GMMG. It's hard to decide because once you buy something, you face the facts that there most likely is something a lot better out there...

C:\Documents and Settings\Rick\Desktop\GMMG_KooksLT-and-cats_02SSdyno.mpeg

C:\Documents and Settings\Rick\Desktop\borla-open_kooksLT-ORY_HPE-S-cam.mpeg

perfect example. Apparently those both have kooks headers and IMO the GMMG sounds much cleaner and deeper.

And on the True dual note. Anyone know of any good Bassani dealers? Their t/d setup seems fairly nice as well. Some say GMMG wouldn't show very effective HP gains?

 

You need to upload those somewhere. You can't link to files on your desktop.
