I'm torn between cat-backs
 
From anyone who has actually owned either of these, which would you say? Magnaflow vs flowmaster? Now everyone relax, not even thinking of putting flowmaster on my car but i have had the experience of having one before :bang: None with magnaflow. So is magnaflow a step up over flowmaster, or should i be looking else where? I'm on a budget and looking for a good cat-back to go with my LT's & catted Y. If money wasn't an issue i'd go back to the Borla exhaust.

True duals man! I wish I would have done it a long time ago.

Order the universal x pipe from summit and have a shop weld it up

If ur on a budget man then I'm telling u to go with the hooker cat back I bought it for my ls1 ws6 and I love how it sounds.

Lawhead May 30, 2011 11:20 PM

LS1 and LT1s sound COMPLETELY different

projectX May 30, 2011 11:22 PM

I heard magnaflow is quiet compared to a 40 series flowmaster

Camaroking1996 May 30, 2011 11:24 PM

I know and I heard them both and they both sounds really good to me

Flowmaster sounds great on an LT1, do that and a cut-out.

This has been on my mind too. What mufflers would you run to have a nice tone? Not necessarily the loudest. Can i have the shop still run them out the rear too, not just dumped at the axle?

I just know it was baddddddd on my ls1 engine.

I've had a hooker catback, true duals, and 2otl on my car. The 2otl is by far my favorite.

Just dump them dude. It's a camaro! I used to be all picky about having a nice exhaust when I had my Borla, but honestly true duals is the only way to go.

You can certainly run them out the back but you're going to have to spend some time / coin to do it. You will need to relocate your stock panhard rod, or get a high clearance one. BMR makes it I think.

I use Borla Pro XS Mufflers. I researched for weeks before I bought mufflers and they are the best balance of sound, and performance on the market I truly believe. The Borla XR-1s are nice, but louder with no real performance gain.

Ha thanks man. This is looking like the cheaper route too! Are you running cats or straight through? Reason I ask is i don't want an annoying tone and I gota play the inspextion game. Here they just plug it in for OBDII testing. Last time not even a visual for cats. But I'd have a year before i find out if i'f fail or not for not having cats, or exhaust tips? Are dumps considered illegal in any technical way :confused:

02v8ta May 30, 2011 11:59 PM

Greg, this the right product/number to go with?

http://www.summitracing.com/parts/BOR-40353/

can't figure out the difference between that one and this..

http://www.summitracing.com/parts/BOR-40359/

err think i just did, offset or centered outlet. Would either work?

gregrob May 31, 2011 12:08 AM

Either should work, I went with the centered outlet since I plan on dumping them.

I love my Hooker Cat-back. Plus I like that I can unbolt my muffler and tailpipes at the 3 bolt flange it has in case I need to service my fuel pump. (Trap door mod would negate this.)

I'm betting given your location that you can't get away with true duals. IF you can, they will make the most power, and can be done the cheapest if you dump them.

The car in the video isn't mine

But I love my tsp rumbler, and it's my favorite catback, except for GMMG

projectX May 31, 2011 11:21 AM

Shit is funny - My bro has a catless LS1 magnaflow CB and I have catless and JUST a V-Force muffler and my shit drowns his @ss out. (V- Force is basically a 40 series flowmaster)

I got my Magnaflow Stainless catback for 311$ shipped brand new. from a distributor.

BizZzatch350 Jun 1, 2011 03:00 AM

I have had a Flowmaster, SLP LM and a Borla. The Loud mouth was my favorite when the car was just bolt ons with the stock cat, sounded really good. I never had it with Long tubes but I imagine it would have been really loud. The Flowmaster sounded decent, I always wanted a Borla so thats why I have it. I have seen magnaflows on a V6 Fcar, seemed like a nice exhaust system.
