and in my opinion the mufflers are too low with them there. unless you like kissing speed bumps. but not good kisses.

I've got some Dynatech's (same things as the XR1)that I bolt up to the headers sometimes and it sounds WAY different than my TD's. It sounds way mean and way loud but it's a bit much to be driving around town with. Ground clearance isn't too bad. The drivers side barely kisses some of the speed bumps but nothing horrible. I bolt it to the header using V-bands so when I welded to v-band to the muffler I put it on there slightly angled so it would point the muffler up a little more, Since that header sorta faces downward

If it's a track car, I'd say go for it if you can fit it... If it's a street car, I'd advise against it...

Too loud inside gets really annoying after a while..

Dynatech Split Flows. I got mine from summit for about $100 a pop. They're pretty similar to the XR1's the only difference is that these have a "cheese grader" going down the middle and they're a little cheaper

No pics. But I have the 3" ones i'm still on old QTP 1 3/4 headers (Custom stepped tri-Y's for a this winters project ). It's a tight fit but BFH mod helps a lot on the driver side. Passenger side tucks up real well. Driver side kisses the speed bumps but never hits hard enough to make me cringe and since I have my TD's on 90% of the time it's no big deal to me.

I bet that TH400 would make me look stupid from a dig. My Mickey Thompsons still can't hook in first. But i'm always up for a challenge

oooh I'm running the kooks 1-7/8 with 3-1/2 collector so I guess i will have to go with the 3-1/2" collector one..

once it gets tune by rick and all little bugs get worked out sounds like a plan on a friendly race..

tell me bout the mickey thompson lost a 3 bill race with those on the m6..
