New spintech super pro street 9000's

After about 5 years of running summit turbo mufflers, one decided to blow a hole in it. At the time i think i got those muffler for $19.95 a piece, so not bad for 5 years of service. I'm not sure if those summit turbo mufflers are directional flow, and they were installed backwards, or these mufflers just flow that much better but throttle responce and just overall starting of the engine is much better when the engine is warm.

anyways here's the old and the new, Same pipes all 3 inch. I'm thinking of doing an X pipe but i still like to have my cutouts for the occational drag strip passes, and i dont think there is room for an x and cutouts.

here are the links:

I had a set of the Prostreets on my prior V8 240Z. Sounded very rowdy! Your sounds really nice with the new muffs!

Re: New spintech super pro street 9000's

I have spintechs on my car and I love them! Can't really get used to the sound of the straight through mufflers... spintechs sound so much better in my opinion! I am really curious about power loss/gain between the two designs.
