After the twins go on and quiet things down a bit Im planning on running 7 inch mitres on my truck. Problem is, all the 5in. T pipes I see reduce to 4 after it goes through the bed. Who makes on that is a full 5 inch the whole way to hook up to my exhaust? Thaks guys!

 

Try contacting Grand Rock, or one of the other site sponsors. My guess is you'll need to piece one together, but hopefully they'll work with you on it.

 

Id contact Garett at www.puredieselpower.com hes a grand rock dealer and has the 5 inch tpipe kits and also 7 inch stack kits.

 

Thanks! Thats just what I was looking for!
