    Just installed TSP Rumbler

    I just got done intalling my tsp rumbler, I already had pace setters and ORY on it along with TSP 228R cam that i had installed last week. When i bought my car it had a flowmaster muffler on it. I thought it would be louder with the Rumbler on it at idle but it isn't, just slightly louder when its revved but they both sound very similar. I guess thats fine though i just wanted to get rid of the chokemaster and put something else on their that would flow alot better. From what i read on here the flowmaster actually took power away from the car vs. the stock setup. The only thing i don't like about the Rumbler is that with its large diameter on the bullet muffler it the lowest thing hanging from the car and i already have a problem scraping my y-pipe and headers when driving over speed bumps, even taking them sideways.

    Damn, i was only expecting like a 10-15 hp gain, i just might see those kind of gains considering the flowmaster was so restrictive.

    So i took the t/a out late last night, i didn't have a chance to take it out right after the install, just started and revved it a few times. And all i have say is damn, the exhaust really woke up my combo. I guess the flowmaster was even more restricive than i thought not allowing my headers to flow. Because i defeniately noticed a seat of the pants difference after the install. I was getting ok traction before but not anymore with my radials on. I was going about twenty and put it to the floor and the tires went up in smoke with out using any clutch. Prior to the install i could do this and still hook up. I'm very pleased with the new exhaust to say the least.
