Went to my muffler man and he said in order to run an aftermarket n1 stye centre/centre muffler, it would either have to be very small to fit into the OEM muffler location or it would have to point downwards. Don't want any of the two so I was thinking instead of running the exhaust around the fuel tank like factory, run it straight and when it meets the gas tank, run it underneath and straight back, then angle it towards where it would normally exit the car under the right side of the rear bumper.

Would this be possible or it would hit the ground?

I shouldn't be lowering too much as I plan to run on 16-17s

If you managed to run a N1 style muffler without it pointing down at the rear exit, please post a pic of how you made this possible..

Thanks In Advance.

It'll probably hit the ground.

I agree. Exhaust routing on these cars is a little tight. I ended up with a muffler where the factory resonator was, ran the rest of the pipes in the stock location till the gas tank, and then just ran it out the side in front of the rear wheel. I was nervous about possibly rubbing, but it hasn't yet.

you will also end up heating your tank up quite a bit. you just need to be creative... i'm running a full 2.25" system with no issues. it helps to have the time to play with it though...

:huh:

The factory routed it directly alongside the front AND right side of the tank to start with....

from factory, it had ample clearance and heat shielding.... (or at least my 94 metro's stock system did... california rated car though...)

it really shouldn't be that hard to make a straight through muffler fit... so long as it is not longer than the space you're squeezing it into, and you have a welder and a bandsaw handy...

you just have to be creative.

Yes, but yours is pointing down, exactly what I'm trying to avoid.

This guy ran his exactly how I mean...He seem to have bent, the piping coming from the muffler itself to get the angle he wanted...

:lol:

That's not exactly a muffler... more of a noise maker.

It's also on a straight plane, it's just placed at an angle pointing away from the center line of the car.

On my 98 I had a 14" long 6" round 2" center to center straight mounted. I just had to shave the bumper down to allow it to fit. A note, I don't have a rear sway bar on that car, I have the suspension set up so as to not need sway bars.
