removed mufflers, gained 2 tenths?

[slow88LX]

i ran my car 3 weeks in a row. the first 2 weeks i ran with my bassani cat-back and pulled a 15.0's with a 2.2 60's. the third week i took off my mufflers just for fun. i ran a 14.8 with a 2.4 60'. i think this is an obvious sign that my mufflers are restrictive? the car just flat out felt like it had MUCH more top end. in fact, when i ran the 14.8 i was running a 96-98 GT and he was ahead of me until the 1/8th where i started pulling on him and passed him by the 1/4.

i think i'm going to order some dynomax bullets. anyone see a problem with this? i want a different/louder sound that the bassani (quiet-thunder???) cat-back i have now



p.s. this was all before i got my gears installed. i now have a new time

Leave the mufflers you have for now thats not the concern you should have. With the gears and a 5 speed you should be mid to low 14's. Use the money to fix that problem. My opinion only...

Also with the mufflers off you will gain some top end, but you WILL loose some low end torque

If you are still running a stock 4 cat h-pipe the BEST after cat exhaust is to have none at all. You have a good amount of back pressure from the cats, enough flow for some decent high end power, and the weight savings is very noticeable....I've been running the open stock H for years and I'm basically in the 12s....damn I need slicks

Got no mufflers either here... Gives a nice sound and when the engine is cold, it gives off some loud pops here and there lol
