i have a set of tti's 1" 7/8,(not the best) i want to know if its a bad idea to bolt a race muffler (kooks or arh type) directly to the flange,i've seen it before i just dont know if its good or bad..i do listen to advice so any would be good.I also was thinking open headers,i'd rather muffled though.

we have done this before with no ill effects , a jetting change was needed as well, also small timing change

most header mufflers hang kinda low. They have to clear the floor of the car. Are you running a muffler class? might be better to clear the bend and hang a set of Moroso Spirals with turn outs on them.

if u bolt to the flange, i'd support the muffler some how to keep the headers from flexing. they may crack from the weight.seeya

Andy,remember the 3 chamber rule at Englishtown I went with the hooker aerochamber which is a straight through muffler available up to 3.5 inches last time I looked

after talkin w my man,i think im gonna try what i have now full exhaust& at the track unbolt and rejet to see if it picks up,gonna be wild ride either way,I do know w the exhause off i'll lose 50lbs + i gotta lose 15 im 220 now lol.

FWIW, I have a 360 with TTI step headers - 1 5/8"-1 3/4" - which I ran open for a couple of years. Then I added a 3" X-pipe and Dynomax Ultraflow mufflers dumping at the rear end housing. I removed the 60lbs the exhaust added to bring it down to the same weight as before and the car was .05-.10 faster!

I figure that the mufflers didn't hurt at all and the X-pipe helped on my particular combo. I may go to their bullet version to save a little weight and gain a little more room around the rear end housing.

Fishy is this for the new bullitt?And how much is it weighing now?........

tiny bit over 3000 w 727tf,putting in ati supercase glide,and yes its for the same motor,different set up though...i have a x pipe on it now w ultra flows,3"...im not a huge fan of the open headers,but i'll try it. thanks

I hear ya. put mufflers on that sucker and let it eat

My 4 inch system is a pain the DIFF to remove.I doubt it would make that much of a difference other than the weight removed
