Exhaust

**Tyler_LS1** · 09-13-2006, 05:24 PM

Ive been thinkin about goin with the MagnaFlow Cat-back and was wondering what you guys thought?

would doublewalled tips sound different than singlewalled tips?

**ss~zoso~ss** · 09-13-2006, 07:20 PM

i dont think the tips would make any different sound, they just look better imho

**ss~zoso~ss** · 09-13-2006, 07:21 PM

i onlly like the look of em on trans ams / firebirds tho

Yea the tips arent gonna make any diff except for appearence, As far as the exhaust setup you can check out ls1sounds.com and see if you like the tone.

The magnaflow is an awesome choice for the price....

Thanks!!

SLP Loudmouth FTW!

my friend has the single tips on his Z28 and it looks/sounds great especially for the price

As far as the loudmouth or magnaflow, they both flow equally well, the only difference is the sound you want. LM's have a good rumble at idle and scream when you get on it, magnaflow is quiet at cruising speed, but when you get on it, it sings.

do a custom TD, catbacks flow pretty much the same. I got a local shop to do TD over axle in all stainless, the only way to go -imo-

**BlackLT1Z28** · 09-15-2006, 02:44 PM

If you do true duals, dumping them before the axle is the only way to go. If you go over axle with the true duals, that's too many bends for what you're going for.

**Tyler_LS1** · 09-15-2006, 03:35 PM

what about clearance issues with true dualls?? how much will i lose?
will i be able to still go over speed bumps?

Thanks!

**BlackLT1Z28** · 09-15-2006, 04:48 PM

Clearance really depends on how well the system is put together and tucked under the car. My headers actually hang pretty far down, but I don't have any clearance issues yet.

If you tuck both dual pipes up in the body the way that the stock pipe runs, you will actually have more ground clearence with the over the axle duals than you had with that stupid "Y" pipe system. You will also pick a nice number of horses over that "Y" pipe system and get a sound that olnly a true dual exhaust system can give.

i am planning on keepin the stock headers for a while, but if i run duals then what diameter pipe should i use so that it will fit?

Thanks!

Wait...you're going to run stock exhaust manifolds and convert to true duals?
That's going to take some extra fab work because you'll have to run the pipes all the way to where the manifolds attach to the Y-pipe. I guess it is possible, but if you decide to get headers later, you'll have to take all that stuff out and start over again. I suggest waiting if you plan on getting headers, especially longtubes. True duals are easier to manage on longtubes.

**Tyler_LS1** · 09-17-2006, 11:35 AM

ya i cant afford headers right now, but the advice was really helpfull i think for now i will just stick with the Y-pipe and get the magnaflow cat-back.

thanks!

**BlackLT1Z28** · 09-17-2006, 04:58 PM

There's really nothing wrong with running a y-pipe setup. They produce more low-end torque over true duals. True duals are favored for their sound qualities and increase in power in the upper RPM ranges. BUt a good header-y pipe-catback setup can sound better than true duals.

If you ever upgrade to LT's, the Magnaflow is a good choice. Buy parts right the first time, so you won't have to do it again in the future!

I agree. But if you really want true duals, I'd hold off on ANYTHING exhaust related so you don't waste any money. Save up and get your LT's, then fab up a dual dual system. No need to buy a catback that you'll replace a year or so in the future.
