I’ve got the BBK 1 3/4 Long tubes but note sure what mid pipe to use.
I’m not seeing many mid pipes that aren’t 3 inch.
Do most guys do customs exhaust from the headers back if you want more than 2.5 inch? Right now I’m thinking to just use dumps instead of tail pipes to shorten the overall exhaust length.
Be careful recommending this. I purchased full 3" exhaust for my build with the same mentality you had and endedup taking it all off when I put on the full MM road and track kit. The torque arm and pan hard bar doesn't like 3" exhaust.
The Summit kits are cheap but you should weld them and trash the old school clamps.. Use V-Bands if you can. They are the only way to go.. YOu can tear down an exhaust in 5 minutes and then put it right back without fighting with crimped pipes..
Nice build. Is the regulator on the shock tower NHRA legal?
I’m considering going lower compression to give me room to add boost later I go back and forth on it.
had to build my entire exhaust system except the tail pipes. Oh and headers, but they needed some work too, I just didn't build them.
Everyone likes flowmaster tails, and they work. Dont' forget Stinger. I use Stinger's tailpipes, almost identical to flowmaster (I use aluminized not SS) but a little less expensive. Two piece tail pipe per side makes it a little easier to install than some of the others. Fitting 3" in there is a chore! Gets very close to the UCA and frame, not a lot of room in there. Mine is a GT with the GT rear bumper cover, so I also had to cut the tips off and put turn downs on it. Expect trimming to fit, nothing is a true bolt-on.
3" is going to be loud. Mine is for sure. Louder than I like. May try different mufflers in the future, may also add a pair of cats. Gonna suck some power out but I do drive it, and often.
the 4 cylinder car? 3" full system from the turbo back, dynomax welded muffler. Not very loud at all, but audible. Barely hear the turbo whistle. Kinda nice. I put about 400 miles a week on it now. Gets a little noisy when the wastegate is open but not bad, the turbo eats up a lot of noise.
I'm using RCI 1 3/4" mid-length headers. MAC prochamber 3" mid-pipe (cut & adapted to the RCI headers using v-clamps)
I used shallow-taper 3" to 2 1/2" reducer pipes before the mufflers. I cut the flow-tubes to allow for the added length of the taper pipe.
Seems as the exhaust cools, it's OK to reduce the diameter to keep the velocity up. I got the flow tubes on Ebay. 3" flow tubes ; and it looks like Flowmaster makes the 3" to 2 1/2" tapered pipes (as mentioned above also.)
Did you find an big offset in joining the headers to the MAC mid pipe? Any pictures?
Thinking about doing the same thing on a 351 in a fox. That is IF MAC will make me the mid pipe.
Thanks in advance.
I finished a custom exhaust build recently. Granted, my engine doesn't take full advantage yet, but I have 1 3/4" MAC headers with V-bands and Flowmaster 200 cell cats into a 3" H-pipe I made, running into some 3" Flowmaster Pro series mufflers, dropping down to a 2.5" set of LMR tails. They clear the MM Panhard with some tweaking of the isolator hangers.
