So I have a 1989 RX7 Turbo II with 3" downpipe, cat delete pipe leading to HKS Hi-Power Silent exhaust. Now let me tell you the HKS exhaust did quiet it down a lot from what it was. Doesn't sound like a jet plane anymore, but when I accelerate hard or come to a big hill and have to give it more gas then the exhaust is still a little too loud.

I am a tuner, not a ricer. I don't want to sound like one. Any help please.

a lot of people swear by the Borla XR-1 has a presilencer

if you have the money racingbeat has a presilencer that works great. alot of guys like it and it makes the car have a very nice clean sound...that does not hurt your ears on hard acceleration

....I would be one of them. It stands up to the heat of rotary exhaust quite well, its not that heavy, and it gives the exhaust a nice deep tone.

I had a Greddy PE hooked up to a stock dp and gutted cat, it wasn't the greatest for performance, but it sounded awesome, when I went to a 3" dp and test pipe, it sounded .... less awesome. I had the Test pipe cut and a 3" Borla XR-1 welded in and it went back to well....you know.

It's pretty tough too, got ran off the road by a Ford explorer and the Greddy was dinged up but the XR-1 was still quite usable and I kept it w/ my RB catback. Sounds almost stock at idle, no drone on the highway, and opens up when you step on it.

Well I have the presilencer from my HKS exhaust, but do I really need another?

Looking to get a presilencer for where my cat delete pipe is. Anyone know where I can get one.
