to those w/ Magnaflow hi-flow cats...

I have Magnaflow hi-flo cats on my STR. There are no direct fit Magnaflow cats. Go to Summitt Racing and order the "spun" (no seams) cats (2 1/2" inlet-outlet) $75 each. They'll wake up your STR like there's no tomorrow. Check my soon to be written thread "Hi-Flow cats/1.5 pulley...just what the DR. ordered".

I'll definitely do that. Going from memory here, which can occasionally be suspect, but I think I read that you and Riski have virtually identical exhaust systems (except for resonator delete?). I intend to replicate it, unless something revolutionary comes along in the next month or two. What kind of total cost, give or take, should I expect?

The Magnaflow cats were $160/pair, Magnaflow x-pipe was $85, Dynomax glass packed resonators were $70/pair, Magnaflow mufflers were $160/pair, and the Mina Galleries Porsch style dual s/s exhaust tips were $120/pair. The 2 1/2" pipe and the installation of all components was approx. $800. Not too bad cost-wise when considering the exhaust modification alone will unleash an estimated 25+ HP and serves as foundation for all other modifications.

Phil, Magnaflow mufflers are made well, fit well, are affordable ($80 each), and emit an authoritve but not too overbearing a note. Price out import exhaust systems...$1200 to $2000+. Their x-pipe apparently fits like it was meant to be there ie. just the right width and length. The Magnaflow hi-flow "spun" cats are the closest to a "gutted out" cat and are only $75/each.

Passenger side cat is breaking apart inside....

I hope someone can help me out on this. My passenger side cat is making a clicking sound when revving the engine or driving. The honeycomb inside I'm guessing is flapping around in there. Now the problem is, whomever had this STR 03' welding the cat to the pipe. Now I'm going to have to cut it off and replace the cat or gut the cat and remove the honeycomb. Any help would be appreciated on what to do. Would it be advisable to replace the messed up cat with the Magnaflow cat? or I have to replace both? ??

How many posts does it take to be able to see photos on this site? I would love to see a pic of the underside of the STR, to have an idea of what I am getting myself into with the exhaust swap...those pics have gotta be around, given all the work that y'all have done already.

Or, if somebody who has done this type of swap could tell me how many pipe segments I will need, that would work as well. I'm not referring to the obvious segments (x-pipe, mufflers, etc.), but to those smaller segments that are needed to connect components. I believe I will be deleting the resonators...so I am also wondering how long that portion is.

Tro on da Magnaflow hi-flow cats
Jag79, for g-d sakes would ya please throw on Magnaflow's hi-flow cats, 2 1/2" pipe, x-pipe, and mufflers already!? You STR guys have no idea of what fun and power yer missing. Yes, your cats are on the way out and stock and aftermarket cats are welded on.

This is a cat-back system from Blueflame. It will kinda show you what you are working with. Where that single muffler is with 2 pipes going in and 2 going out would be where the resonator is. Hope this helps some.

Also wondering now if I will have to buy hangers, to weld on to these universal pipes (if they are in fact universal).
