Default Wanting a 5" stack.

Hey guys. First off, I'm proud to say I just got off ebay, and I picked up (all new in their boxes) a 2 gauge pod, an autometer pyro gauge, an autometer boost gauge, and 3200 VE gov spring for less than 2 hundy...what's up. Anyhow I really want to run a 5" stack, but I haven't gone to 4" exhaust yet. My question is, do I have to buy a whole 4" exhaust kit ,then junk half of it when I get the stack kit, or is their a way around this?? Any info will be apreciated.

the flex pipe is necessary so the exhaust pipe wont crack from the twisting of the engine and not so much the frame...it took me a while to believe it but it is true.

Grand Rock can get you a single stack kit...they are a sponsor on here hit them up with a PM or ask all the sponsors to give you a quote here
