I am a fan of MBRP...

 

Me too. Fits well and installs easy. I bought the band clamps instead of the standard exhaust clamps they provide. If I were to do it again, I would either go with the high grade Stainless or just the aluminized. The 409 stainless shows rust spots pretty bad.

 

I bought a 4 inch turbo back exhaust from Jegs, cost approx 300.00 dollars. Exhaust shop welded on hangers. Real happy so far

 

what about banks and bully dog ??

 

i got my 4 inch straight pipe for my 01 cummins from T & J's Diesel Performance Home Page , i got mine for about 220 for the aluminized. looks like they have bullydog all they up to 6 inch, the diamond eye kits, and AFE pipe kits. looks like good deals, best i found at the time when i bought mine. it only took about 20 minutes to install in a parking lot in the dark. went home and welded on a tip and thacked the joints. im happy with it.

 

I'm running the 5" Expandit on my Truck. It comes with U-bolts and saddle clamps, but I remedied that with some welding and cutting of hangers. It's a little more work, but it really looks allot better, and it sounds perfect for my taste.

BUllydog is the best.

 

MBRP man here. Super easy install. It is way harder getting the old one off. Have a sawzall handy.
