Oh, the vacuum lines that run back there. I pulled mine out and put on shelf and capped at the solenoid.

Well, let's see, i have a "few" days on my GT3 stock center (steel) and it's in good order. The TI center it cracks easily.

Don't use the top holes, those must be plugged. Only use the bottom holes. If you see the internal design you'll know why (on the center muffler)

cool, thanks for the info...maybe in my future. do you know your dB readings from those tracks? side muffler delete would sound the same as WOT, right? since the valves open when you're WOT

I had reinforcements welded on my oem muffler for peace of mind when I installed the side muffler delete. If you search under my handle the thread should pop up showing pictures of the reinforcements.

I live in TX so no noise restrictions here but I do drive my car to the track so I don't want a headache after 2-3 hours from Dallas to COTA.

Is the solution to get a stock center muffler and delete the two sides?

CosmosMpower

Wow how did your car weigh so little to start? My car has almost no options and it's heavier than that.

I already have light seats, light wheels, center muffler delete and I'm still at 3200+ granted more gas in the tank and some crap in the car (tools etc).

I don't think 100 pounds on a 3200 pound car is going to make much difference.

Enjoy the radio, the seats and the quiet

Every few tenths/hundredths count. I figure light battery can cut 40, taking out pass side seat and hardware 40, run 1/4 tank of gas 25, take out tools and extra crap 20 so that's 125 should get me down to 3,100ish.

i could never hear the radio to start, gt2 seats weren't comfy, and it was never quiet

awesome, thanks!

LOL

Fritz Flynn

I hear you!

I'm just lapping in DEs with the GT3 so the lap times won't matter much to me.

maybe i'm just getting old

Fritz Flynn

Hell that's what I was thinking about myself

My car currently has a triple disc carbon tilton clutch with LWF, side and center muffler delete and it's a nightmare for street use. Great for a TT car though however this isn't the car to TT, race or do anything but DE and CC LOL

Why not remove the heavy side mufflers - they're close to 25-30 pounds each, and leave the stock center. Car will mostly sound same, and pick up some hp/torque.

Other things I've seen people delete is the sunroof delete - supposedly saves 50 lbs.

I never use the sunroof anyway - just wondering how much that would cost to swap out. You already have a cage, so carbon -fiber would be an option as well.

I might do that but I don't have a stock center muffler anymore. Let's say the side mufflers are 50 lbs total. I'm guessing the center muffler is also 20-25 lbs vs 5-10 for a bypass pipe. Net is probably 25 lbs savings.

Sunroof delete requires quite a bit of body/paintwork which I'm not willing to do. But it would be nice to save 50 lbs at the highest point of the car. I'm looking for low hanging fruit to shave off maybe 100-150 lbs.

Battery, removal of tools/extras, removal of pass seat and running on 1/4 tank of gas should get me most of the way there hopefully.
