hope so I never like that dam oem clamp, as noted it's never tight enough, doesn't matter how many ugga ugga's you do

on my 00 I even ended up replacing the flanges, more than once I would warp them every few years
only place to find them is the junkyard

I think mine still leaks haha but eh, I don't hear it so blah.

the smoke test on mine was leaking pretty good even if it's only a tiny leak I don't need it giving me more brain damage than I already self inflicted lol

I have an AP muffler, and I think it may have been the same one. It definitely has less drone than the MBRP clone muffler I have installed now, but it quiets down the overall sound as well. I wish I could have my current sound, but less interior drone.

Might buy that QW muffler and play around.

The other thought is to buy the short version, but also grab another short, but wider, muffler/resonator in case the QW muffler is obnoxious. I wish mufflers had a strong 2nd-hand market like gun parts, lol.

Do you have headers? I have long tubes, so that adds to the growl.

Just cast iron manifolds. Not ready to throw $$$ at LT headers, welding in cats, and a new tune when I just got the last iteration of my tune running decent.

Happy Halloween

Ignition cylinder suddenly got sticky the last week or so, this is gonna be fun, the spare "unworn" key works slightly better but decided to replace the whole thing and got a new key cut. Instructions kinda don't make sense because the key code has more numbers than the cylinder has slots for

Just going to do it like this, pretty fail safe

Does anyone know who makes the Summit Racing branded ignition coils?


Changed plugs and wires in Deathscalade this morning. My 17 yr old was helping and a coil broke on him as he was taking a wire off. Long story short, for now I’ve replaced that coil with a Standard Ignition coil from the O’Reilly. Long term, I’m going to replace all of them so that they all match. Looking on the Summit Racing interwebz and the Summit Racing kit is $100 or more cheaper than MSD so had me curious as to made them for them.


Edit: went over to Jegs and these Mishimoto units popped up. I may give these a gander
