 BPS-Q vs MAC exhaust
I've had a BPS Q on the back of my PD for several years now and it has started leaking around the muffler. The noise sounds like a valve tapping and is very annoying. I am planning on changing out the exhaust soon. I've been happy with the BPS exhaust and am not looking for a loud exhaust. I'm deaf enough without the extra help.
I have read a few comments on the MAC exhaust and had a few questions about them.
1. What is the cost compared to a BPS 2. How have they been holding up. I ask this because I know people with Marsh Mellow that are constantly replacing the bands. 3. Is it comparable in dB to the BPS?
Thanks for the input.

 Re: BPS-Q vs MAC exhaust
All performance exhaust is over priced. The Q is about 100.00 cheaper than the MAC.

 Re: BPS-Q vs MAC exhaust
you guys can really see a gain in bottom end performance from an exhaust.

 Re: BPS-Q vs MAC exhaust
The MAC even with baffles is still substantially louder then the Q. It does appear the MAC is built really well from what I have seen.

 Re: BPS-Q vs MAC exhaust
Mac is well built. The unbaffled is extremely loud, but so is a gutted stocker

 Re: BPS-Q vs MAC exhaust
Unless the 'Q' is really damaged, why not just have it welded up? (save the $$ for headwork)
